POLYGONS
Objectives:
1. To identify polygons and their classifications
2. To name a polygon
3. To solve the area, sum of the interior angles, and the measure of the central angle of a polygon.
A closed plane figure formed by connecting three or more segments at their endpoints is called polygons. A Polygon comes from Greek. Poly- means "many" and -gon means "angle". They are made of straight lines, and the shape is "closed" (all the lines connect up). The segments are the sides of the polygon while the endpoints of these polygons are the vertices of the polygon. Two sides of a polygon are adjacent (or consecutive) if they have a common endpoint. Two angles of a polygon are adjacent (or consecutive) if they are the endpoints of a side.
In the figure above, the endpoints A, B, and C are vertices of the polygon and the segments AB, BC, and CD are the sides of the polygon. The angles of the polygon are CAB, ABC, and BCA.
Types of Polygons
Regular or Irregular
If all angles are equal and all sides are equal, then it is regular, otherwise it is irregular

Concave or Convex
A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°.
If any internal angle is greater than 180° then the polygon is concave. (Think: concave has a "cave" in it)
Simple or Complex
A simple polygon has only one boundary, and it doesn't cross over itself. A complex polygon intersects itself! Many rules about polygons don't work when it is complex.
Simple Polygon(this one's a Pentagon)
Complex Polygon(also a Pentagon)
CONCAVE POLYGON
The figure at the left side is an example of a CONCAVE POLYGON because it has an internal angle whose measure is
greater than 180˚ degrees.

Example: a 62-sided polygon is a Hexacontadigon
BUT, for polygons with 13 or more sides, it is OK (and easier) to write "13-gon", "14-gon" ... "100-gon", etc.
The total space inside of any polygon which is enclosed by the line segments is called the area of a polygon. An interior angle of a polygon is an angle on the inside of a polygon formed by each pair of adjacent sides. A central angle is an angle formed by the segments joining consecutive vertices to the center of a regular n-gon. The center of a circle in which a regular polygon is inscribed is called the center of the polygon. An exterior angle is an angle formed by a side of the regular n-gon.
A diagonal of a polygon is a segment joining two consecutive vertices of a convex polygon.

Apothem
The formula to be used for finding the area of any convex polygon is given by A = ½ Pa, where P is the perimeter and a is the apothem.
The formula used for finding the sum of the interior angles of any convex polygon is given by S = (n – 2) 180˚.
The formula to be used for finding the measure of the central angle of any convex polygon is given by θ = 360˚/n, where n is the number of sides of any
7
Example
Find the area, sum of the interior angles, and the measure of the central angle of a convex pentagon which has a side of 3 cm long and an apothem of 2.5 cm.
Solution:
To solve the area of a pentagon, we need to find first its perimeter and the length of its apothem.
Given: s = 5cm, apothem = 2.5 cm, and a pentagon has 5 sides
Perimeter (P) = the sum of the lengths of the sides of a polygon
Or since the lengths of the sides of a polygon are all equal, so we can also use this formula for the perimeter of any polygon P = ns, where n is the number of sides and s is the length of a side.
P = 5 cm + 5 cm + 5 cm + 5 cm + 5 cm
P = 5(5 cm)
P = 25 cm
Solve for the area
A = ½ Pa = ½ (25 cm) (2.5 cm) = ½ 62.5 cm2 = 31.25 cm2
Solve for the sum of the interior angles
Using the formula for the sum of interior angles of a polygon, we have
ΘI = (n – 2) 180˚ = (5 – 2) 180˚ = (3) 180˚ = 540˚
Solve for the measure of the central angle of a polygon
Using the formula for the central angle of a polygon, we have
ΘC = 360˚/n = 360˚/5 = 72˚
The formula to be used for finding the area of any convex polygon is given by A = ½ Pa, where P is the perimeter and a is the apothem.
The formula used for finding the sum of the interior angles of any convex polygon is given by S = (n – 2) 180˚.
The formula to be used for finding the measure of the central angle of any convex polygon is given by θ = 360˚/n, where n is the number of sides of any
8
Therefore, the area of the polygon is 32.25 cm2, the sum of its interior angles is 540˚, and the measure of its central angle is 72˚.
Triangles
Objectives:
1. To identify triangles according to the number of congruent sides and according to their angles.
Classification of Triangles
Triangles can be classified according to the number of congruent sides
Triangles can also be classified according to their angles
Scalene Triangle
No two sides are congruent
Equilateral Triangle
Three sides are congruent.
Triangle is a polygon with three sides. If a triangle has vertices C, D, and E. we name the triangle as triangle CDE, or in symbols, ∆CDE. In the figure at the right, the line segments CD, DE, and CE are the
sides of the triangle while the ∠CDE or ∠D, ∠DCE
or ∠C and ∠DEC or ∠E are the angles of the triangle.E

QUADRILATERALS
Objectives:
1. To illustrate quadrilaterals
48˚6
Right Triangle
One angle is a right angle.
leg
leg
HypotenuseThe side opposite the right angle of a right
triangle is called the hypotenuse. The two sides are called the legs.
Equiangular Triangle
All angles are equal.
The measures of each of the interior angle of an equiangular triangle are always equal to 60˚.
60˚ 60˚
60˚
10
2. To define and illustrate the types of quadrilaterals
3. To differentiate the types of quadrilaterals
Quadrilateral just means "four sides" (quad means four, lateral means side).
Any four-sided shape is a Quadrilateral.
But the sides have to be straight, and it has to be 2-dimensional.
Properties
Four sides (edges) Four vertices (corners) The interior angles add up to 360 degrees:
Try drawing a quadrilateral, and measure the angles. They should add to 360°
Types of Quadrilaterals
There are special types of quadrilateral:
Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms.
11
The Rectangle
means "right angle"
and show equal sides
A rectangle is a four-sided shape where every angle is a right angle (90°).
Also opposite sides are parallel and of equal length.
The Rhombus
A rhombus is a four-sided shape where all sides have equal length.
Also opposite sides are parallel and opposite angles are equal.
Another interesting thing is that the diagonals (dashed lines in second figure) meet in the middle at a right angle. In other words they "bisect" (cut in half) each other at right angles.
A rhombus is sometimes called a rhomb or a diamond.
The Square
A square has equal sides and every angle is a right angle (90°)
Also opposite sides are parallel.
A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
Means “right angle”
Show equal sides
12
The Parallelogram
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles "a" are the same, and angles "b" are the same).
NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Example:
A parallelogram with:
all sides equal and angles "a" and "b" as right angles
is a square!
The Trapezoid (UK: Trapezium)
A trapezoid has a pair of opposite sides parallel. It is a quadrilateral with exactly one pair of opposite sides.
It is called an isosceles trapezoid if the sides that aren't parallel are equal in length and both angles coming from a parallel side are equal, as shown.
13
And a trapezium is a quadrilateral with NO parallel sides:
The Kite
A kite has two pairs of sides. Each pair is made up of adjacent sides that are equal in length. The angles are equal where the pairs meet. Diagonals (dashed lines) meet at a right angle, and one of the diagonal bisects (cuts equally in half) the other.
PERIMETER OF POLYGONS (TRIANGLE, RECTANGLE, SQUARE, and PARALLELOGRAM)
Objectives:
1. To determine the perimeter of a polygon
2. To solve problems involving perimeter
The perimeter is the distance around a polygon.
PERIMETER OF A TRIANGLE
The perimeter of a triangle is the sum of the lengths of its three sides.
The perimeter of a triangle with sides a, b, and c is given by
P = a + b + c
14cm
17cm7cm
Example
A triangular piece of paper measures 7cm, 14cm, and 17cm. What is the perimeter of the piece of paper?
Solution:
Using the formula for the perimeter of a triangle, we have
P = a + b + c = 7cm + 14cm + 17cm = 38cm Therefore, the perimeter of the paper is 38cm.
14
PERIMETER OF A RECTANGLE
Example
PERIMETER OF A SQUARE
P = 4s
Where s = length of the side of a square
Width (w)
Length (l )
The perimeter of a rectangle is the sum of twice its length and twice its width
The perimeter of a rectangle with length l and width w is given by
P = 2l + 2w
Solution:
The problem asks for the perimeter of the tablecloth. Using the formula for the perimeter of a rectangle, we have
P = 2l + 2w = 2(4.5m) + 2(2.5m) = 14m
Therefore, 9m of the lace trimmings should be bought.
4.5m
2.5m
A rectangular tablecloth has a width of 2.5m and a length of 4.5m. How meters of lace trimmings should be bought to make its border?
Solution:
Using the formula for the perimeter of a triangle, we have
P = a + b + c = 7cm + 14cm + 17cm = 38cm Therefore, the perimeter of the paper is 38cm.
Since the sides of a square are of equal lengths, its perimeter is four times the length of a side.
The perimeter of a square with side s is given by
15
AREA OF SOME PLANE FIGURES (TRIANGLE, RECTANGLE, SQUARE, PARALLELOGRAM, TRAPEZIOD)
Objectives:
1. To derive and find the area of a rectangle, square, triangle, parallelogram, and a trapezoid.
2. To use square units when finding area.
Area of a closed plane figure is the measure of the region (surface) enclosed by its boundary or the line segments.
Area of a Rectangle
The area of a rectangle is the product of its length and width.
The area of a rectangle with length l and width w is given by
A = l x w
Solution
The problem asks for the perimeter of the mat. Using the formula for the perimeter of a square, we have
P = 4s = 4(50.5 cm) = 202 cm
Therefore, 202 cm long of lace material is needed to borders the mat.
50.5 cm
Example
One side of a square mat is of length 50.5 cm. How long of a lace material is needed to put borders on it?
Width (w)
Length (l)
2 m
Example
A rectangular garden has a length of 5 m and a width of 2 m. What is its area?
Solution:
Since the garden is in rectangular formed, use the formula for the area of a rectangle.
A = l x w = 5 m x 2 m = 10 cm2
Therefore, the area of the rectangular garden is 10 m2.
16
Area of a Square
Area of a Triangle
The area of a triangle is one half of the product of its base and height.
The area of a triangle with base b and height h is given by
A = ½ bh
Example
The base of a triangular flaglet is 10 cm long. If the height of the flaglet is 4.2 cm, what is its area?
s
s
s
s
base
h
5 m
Since the lengths of the sides of a square are all equal, so its area must be the product of its two sides or the square of a side.
The area of a square with side s is given by
A = s 2 where s is the length of the side of a square
Example
What is the floor area of a square room which measures 6.5 m on each of its sides?
Solution:
Using the formula for the area of a square, we have
A = s2 = (6.5 m)2 = 42.25 m2
Therefore, the floor area of the room is 42.25 m2.
6.5 m
17
Solution:
Using the formula for the area of a triangle, we have
A = ½ bh = ½ (10 cm x 4.2 cm) = ½ 42 cm2 = 21 cm2
Therefore, the area of the flaglet is 21 cm2.
Area of a Parallelogram
The area of a parallelogram is the product of its base and height.
The area of a parallelogram with base b and height h is given by
A = bh
Area of a Trapezoid
The area A of a trapezoid of height h and bases b1 and b2 is given by
A = ½ h(b1 + b2)
b

25 m
42 m
Example
A rice field is in the shape of a parallelogram. If its base is 42 m and its height is 25 m, what is its area?
Solution:
Using the formula for the area of a parallelogram, we have
A = bh = (42 m) (25 m) = 1050 m2
Therefore, the area of the rice field is 1050 m2
Example
h
b2
b1
Since the lengths of the sides of a square are all equal, so its area must be the product of its two sides or the square of a side.
The area of a square with side s is given by
A = s 2 where s is the length of the side of a square
Example
What is the floor area of a square room which measures 6.5 m on each of its sides?
Solution:
Using the formula for the area of a square, we have
A = s2 = (6.5 m)2 = 42.25 m2
Therefore, the floor area of the room is 42.25 m2.
