Sample Response: 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. What did you include in your response? Check all that apply.Congruent, corresponding side lengths are needed.The triangles need corresponding, congruent sides to be congruent.Once congruent sides are known, the AS
