What is SSS

100

The interior angle sum of an 18-sided polygon.

What is 2880 degrees?

200
Two equal sides and angles
What is Isosceles
200
The value of all three angles in a triangle added together.
What is 180 degrees
200

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

What is SAS

200

The interior angle sum of a dodecagon.

What is 1800 degrees?

300
All sides and angles are equal.
What is Equilateral
300
When two lines intersect the opposite angles are equal to each other.
What is vertical angles
300
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
What is ASA
300
The two sides of a right triangle that form the 90 degree angle.
What are the legs
400
Has an angle whose measurement is greater then 90 degrees.
What is Obtuse
400
The little box in the corner of a triangle.
What is 90 degrees.
400
If two angles and the non-included side one triangle are congruent to two angles and the non-included angle of another triangle, then these two triangles are congruent.
What is AAS
400
It states if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
What is Hypotenuse-Leg Theorem
500
All angles measure less then 90 degrees.
What is acute.
500
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
What is Exterior Angle Theorem
500

If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.

What is SSS

500
Besides one angle you need this number of sides to prove a right triangle congruent?
What is two.
