Please rephrase your question. It doesn't make a lot of sense.
There are two theorems for triangle congruency that involve two congruent angles. These are Angle, angle, Side and Angle, Side, angle.
Once again, please clarify your question and I'll try to help you more. Thanks!

What are the initial conditions of the proof? Is this an isosceles triangle, or did we prove the triangles congruent already or any other number of reasons. If you'll post the initial conditions then I can help you. Thanks!
