100
The 8 interior angles of an octagon add up to this amount.
What is 1080?
200
The two congruent sides of an isosceles triangle form this angle.
What is the vertex angle?
200
If you already know that two triangles are congruent, then the corresponding sides and angles are congruent because of this theorem.
What is CPCTC?
200
A segment that is drawn from a vertex of a triangle that is perpendicular to the opposite side.
What is an altitude?

This is true of the opposite angles of a parallelogram.
What is they are congruent?
200
The 12 exterior angles of a dodecagon add up to this amount.
What is 360?
300
The side opposite the right angle in a right triangle - it is also the longest side of a right triangle.
What is the hypotenuse?
300
One of these is NOT a pattern used to get triangles congruent: ASA, SSS, AAS, SSA, HL, SAS.
What is SSA?
300
A segment that connects the midpoints of two sides of a triangle.
What is a midsegment?
300
This is true of the consecutive angles of a parallelogram.
What is supplementary, or add up to 180?
300
A parallelogram with 4 congruent sides.
What is a rhombus?
400
The two sides of a right triangle that are not the hypotenuse - they make up the right angle.
What are the legs?
400
Triangle ABC is congruent to triangle MNQ. Angle B will be congruent to this angle in triangle MNQ.
What is angle N?
400
When three or more lines intersect at the same point, they are known by this term.
What is concurrent?

One of the two things that are true about the diagonals of a rectangle.
What is congruent, or bisect each other?
400
If two angles of a triangle measure 43 degrees and 54 degrees, this will be the measure of the remaining angle.
What is 83?
500
The two angles of an isosceles triangle that are opposite the congruent sides.

What is side FD?
500
A polygon of seven sides.
What is a heptagon?
500
