Geometry: How can we prove two triangles are congruent?

Geometry:  

Let's add two more postulates to help use prove two triangles are congruent: A.S.A. and A.A.S. Complete two-column proofs using definitions and relationships between certain angles in the triangles. Analyze diagrams and decide whether there is enough information to prove two triangles congruent; if so, could you use S.S.S., S.A.S., A.S.A., or A.A.S.
