A polygon is a flat, closed plane shape made up of three or more

line segments called sides

TRUE OR FALSE:

A QUADRILATERAL IS A POLYGON WITH TWO SIDES

A QUADRILATERAL IS A POLYGON WITH FOUR SIDES

A SIX SIDED SHAPE IS CALLED A _________?

WHAT ARE THE NAME FOR

QUADRILATERALS WITH FOUR EQUAL

SIDES?

A SQUARE AND A RHOMBUS!!

SQUARE

RHOMBUS

NAME THE GEOMETRIC FIGURE EACH SIGN REPRESENTS:

Octagon Rectangle Triangle

CIRCLES ARE A TYPE OF POLYGON?

A CIRCLE IS CURVED, NOT FLAT, AND IS NOT MADE UP OF

ANY LINE SEGMENTS.

A line is a straight path that extends in two directions.

Do Perpendicular Lines Interest at:

• RIGHT ANGLES

• ACUTE ANGLES

• OBTUSE ANGLES

When perpendicular lines intersect, they create right angles.

Right Angle

Which is an example of parallel lines?

A:

B:

C:

B:

Parallel lines do not intersect

If given the name <ABC, which angle is correct?

A

C: A

C B

A:

A

C

Since B is the middle letter in the angle name, <ABC, B has to be the vertex of the angle.

Which direction would ray MB need to be moved to make an obtuse

angle?

B

M R

Ray MB would need to be moved to the left, to make an

obtuse angle because an obtuse angle is greater than

90 degrees.

Congruent figures are the same shape, but can be

different sizes?

Congruent figures are the same shape AND size.

If two figures are similar, are they

A: The same shape, but different sizes?

B: Different shapes, but the same size?

A: The same shape, but not necessarily the same size.

Similar figures have to be the same shape, however, they can be the same or

different sizes.

Are these figures:

•Congruent

•Similar but not congruent

•Neither

The figures are similar because they are the same shape, but not the

same size.

Do all figures have a line or lines of symmetry?

All figures do not have a line of symmetry.

Has line of symmetry

Does not have symmetry

What is another name for a line of symmetry?

A: A curved line

B: A diagonal line

C: A perfect line

D: A fold line

Another name for a line of symmetry is a FOLD LINE!

A line of symmetry separates a figure into

two parts that math exactly. You can FOLD

a shape along the line(s) of symmetry and

the pieces will lay directly on top of another.

How many lines of symmetry does this figure have?

A: One

B: Three

C: Four

D: Five

Which triangle is an equilateral triangle?

A B C

A scalene triangle has three sides and angles that are

equal?

Letter A: Is an equilateral triangle

An equilateral triangle has

three sides and angles that are

equal.

FALSE!!!!!

A scalene triangle has NO sides or angles that are equal.

An equilateral triangle has three sides and angles that are equal.

SCALENE EQUILATERAL

The Answer is B: FIVE

Another name for a translation is a “step”

Another name for a translation is a SLIDE!!

A translation is when you move a figure up, down, or over.

WHICH IS AN EXAMPLE OF A REFLECTION:

A B C

A reflection is when you FLIP an object over a line. Think of the object looking “opposite” or think of a “mirror effect.”

A:

A radius of a circle is half the length of the diameter?

A

B

The radius is a line segment whose end points are the center of the circle

and a point on the circle.

What is the name of the circle below?

A: Circle MS B: Circle A C: Circle MSA

M

A

S

B: Circle A

A circle is named by its center point. This is circle A

Which circle shows the diameter?

A B C

A

B

A

BA B

Circle B shows the diameter

The diameter of a circle is a line segment that goes trough the center of a circle and whose end points are

on the circle.

A B

AB

If the radius of the circle is 2, how long would the diameter be?

AB

The radius is half the length of the diameter so if the radius is 2, the diameter would be 4!!!

C
