Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

What is the included side in a triangle?

Back

The included side is the side that lies between two angles in a triangle.

Front

True or False: The included angle is the angle formed by two sides of a triangle.

Back

True

Front

Which triangle congruence theorem is used when two sides and the included angle are known?
