If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of a second triangle, then the triangles are congruent (AAS)

Given

Triangles ABC, EFG
If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of a second triangle, then the triangles are congruent (AAS)



AC = EG

Prove
 


Proof
1:
- Given
2: - From 1  - If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent

3: AC = EG - Given

4: - From 1,2,3 - If two angles  and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent (ASA).
