Section 21.2: AAS Triangle Congruence

Objective: By following instructions, students will be able to: Use the AAS Triangle Congruence Theorem.

RECALL: If sides are congruent and angles are congruent, then triangles are congruent.

Angle-Angle-Side (AAS) Congruence Theorem

explain 1 Prove the AAS Congruence Theorem

explain 2A Use the AAS Theorem to prove the given triangles are congruent.

explain 2B Use the AAS Theorem to prove the given triangles are congruent.
