Front

Define the Side-Side-Side (SSS) Congruence Postulate.

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the Angle-Angle (AA) Similarity Postulate?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the definition of complementary angles?

Back

Two angles are complementary if the sum of their measures is 90°.

Front
