One sandwich has a side length of 2 inches. To show that ED GF, look for a pair of angles that are congruent. Download ppt ” Triangle Congruence: One angle pair is congruent, because they are vertical angles. SAS Steps 2, 4, 3 5. Practice C Write paragraph proofs for Exercises 1 and 2.

Congruent segments have equal lengths, so the diagonals bisect each other. J The triangles are not congruent. Write a conjecture about the diagonals of a square.
