Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape.

Front

What is the ASA congruence criterion?

Back

Angle-Side-Angle: 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.

Front

What is the AAS congruence criterion?

Back

Angle-Angle-Side: If two angles and a non-included side of one triangle are equal to two angles and a corresponding non-included side of another triangle, the triangles are congruent.
