If two triangles have three congruent, corresponding angles, what additional information is needed to prove that the triangles are congruent?
To prove that two triangles with three congruent, corresponding angles are congruent, you would need to have at least one set of corresponding sides that are also congruent. You could then use ASA or AAS congruence theorems or rigid transformations to prove congruence.
