A student writes the statement angle BEA=~angle DEC to help prove the triangles are congruent what reason should the student give?
Answered by Steve
well, the angles must be congruent if the triangles are.

You need 3 things (sss, sas, aas, asa, or for right triangles HL) to prove a triangle is congruent, Steve is incorrect just because the angles are congruent doesn't mean that the triangles are.
Answered by Steve
not so. The triangles cannot be congruent unless all the angles are congruent. Proving that these two angles are congruent could certainly help in the proof that the triangles are congruent.

I did not say that this single step is a proof.
