Define: Polygon
Answer
Back
Polygon - A simple, closed, 2-D figure made up of three or more line segments.
Polygons for $100
Give every possible name for a square
Answer
Back
Square, rhombus, rectangle, parallelogram, quadrilateral, polygon
Polygons for $200
Give the best name for the figure with the following properties:
Opposite sides are parallel and congruent
Answer
Parallelogram
Back
Polygons for $300
Give the best name for the figure with the following properties:
The diagonals bisect each other and are perpendicular
Answer
Rhombus
Back
Polygons for $400
What is the formula for the number of degrees in any polygon and where does it come from?
Answer
Back
Degrees = (n-2)*180, where n is the number of sides in the figure
It comes from drawing all the diagonals from one vertex (breaking the shape into triangles)
Polygons for $500
Quadrilaterals are broken into three groups for naming based on one property. What is that property?
Answer
Back
The number of parallel sides
Congruencefor $100
What are the three ways to determine if two triangles are congruent using only three pieces of information?
Answer
SSS, ASA, SAS
Back
Congruence for $200
What does CPCTC stand for?
Answer
Back
Corresponding parts of congruent triangles are congruent. In other words, if two triangles are congruent then the angles and sides that are in the same position on each triangle are also congruent.
Congruence for $300
Are the two triangles congruent? If so, how do you know?
Answer
Yes, they are by SAS. Two sides are given as congruent and the included angles are congruent because they are vertical angles
Back
Congruence for $400
Are the two triangles congruent? If so, how do you know?
Answer
Not necessarily. Although they could be congruent, there is not enough information to tell for sure. SSA is inconclusive.
Back
Congruence for $500
Are the two triangles congruent? If so, how do you know?
Given: AB bisects angle A
A
BC D
AnswerYes, they are congruent by SAS. One pair
of sides are congruent (given). Side AB is congruent to itself, and the angles CAB and DAB are congruent (definition of angle bisector.

Circles for $100
Where does pi come from?
Answer
The circumference of a circle divided by the diameter of a circle.
Back
Circles for $200
Define: Circle
Answer
Back
The locus of all points equidistant from a given point (the center)
Circles for $300
What is a central angle?
Answer
Any angle whose vertex lies on the center of the circle
Back
Circles for $400
The circumference of a circle is 10cm. To the nearest tenth, what is the radius of the circle?
Answer
C = 2(pi)*r
10 = 6.28r
r = 1.6cm
Back
Circles for $500
Given that a sector is 55% of a circle, how many degrees are in the central angle of the sector?
Answer
0.55 = 360x
x = 198 degrees

Transformations for $100
What is the name of the picture of a figure prior to a transformation being done on it?
Answer
The pre-image
Back
Transformations for $200
What are the two pieces of information you need to be given in order to rotate a figure. (assume the figure is already given)
Answer
The angle of rotation and the center of rotation
