Explain the mistake in each proof in Problems 1-2. Then describe a correct way to prove that the triangles are congruent. Identify any additional information that is needed. Given: FD BC, AB DE, and AC FE. Since FD BC, ZDFE = ZACB by the Alt. Int. Thm. Since AB || DE, ZABC = ZEDF by the Alt. Int 2 Thm. Also, AC = FE is given. Therefore, AABC = AEDF by AAS Congruence Theorem.
