What is SSS
100

The number of 90 degree angles in a right triangle.

What is one?

100
Has two congruent sides called legs.
What is Isosceles Triangle
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 sum of the two acute angles in a right triangle.
What is 90 degrees
200
All three sides are congruent.
What is Equilateral Triangle
300

All sides and angles are equal.

What is Equilateral and Equiangular?

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
300
All three angles equal 60 degrees.
What is Equiangular.
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
400
The non congruent side of an isosceles triangle.
What is a base
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.
500

The point where two sides come together.

What is Vertex Angle
