Two triangles are congruent because two pairs of corresponding sides and the included angle are congruent
What is SAS?
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
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
Two angles of a triangle and the included side are congruent to the corresponding angles and sides of another triangle.
What is ASA
300
All three angles equal 60 degrees.
What is Equiangular.

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
A part of a triangle that is congruent to itself
The reflexive property
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?
