Front

Define the SSS Postulate.

Back

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

Front

Define the SAS Postulate.

Back

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

Front

Define the ASA Postulate.

Back

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

Front

Define the AAS Theorem.

Back

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