Points, Lines, and Planes for $500
Define: Polygon
Answer
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
Square, rhombus, rectangle,
parallelogram, quadrilateral,
polygon
Back
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
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)

Quadrilaterals are broken into three
groups for naming based on one
property. What is that property?
Answer
The number of parallel sides

Congruence
for $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
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.
Back
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
D
C
B
Answer
Yes, 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
The locus of all points
equidistant from a given point
(the center)
Back
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
Back
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
