Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in size and shape.

Front

What is the Angle-Side-Angle (ASA) congruence postulate?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.
