Proving Triangle Congruence: SSS, SAS, ASA, AAS

What does the Side-Side-Side (SSS) postulate state?

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

• 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.

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

• 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.
