try teachers.net.. they post different creative lessons
Don't you extend the sides and prove all the little triangles equal and therefore the angles are congruent? Or are you trying to prove 2 different triangles congruent?
thanks everyone. I am looking into it. It is proving 2 different triangles congruent. sometimes it is two parts of one triangle. thanks again.
