Proving Congruence – ASA, AASChapter 5.3
Use ASA in proofs Statements Reasons
AAS Postulate Angle-Angle-Side Congruence If two angles and a non included side of one triangle are congruent to the corresponding two angles and side of a second triangle then the triangles are congruent
Use AAS in proofs Given: Prove: Statements Reasons
HL Example Statements Reasons Angle RVS is right
Example Statements Reasons
Example Given: Prove: Statements Reasons Given: QP is parallel to SRProve: QR is congruent to PS

Proving Triangles Congruent
5.4 Hypotenuse – Leg Congruence Theorem: HL
7.4 A Postulate for Similar Triangles. We can prove that 2 triangles are similar by showing that all 3 corresponding angles are congruent, and all 3 sides.
