Best ResponseYou've already chosen the best response.1There is no mention of congruent angles in the body of the proof. There are three pairs of congruent sides. So, I would go with your choice of b if b represents SSS Postulate.

Best ResponseYou've already chosen the best response.0Correct. b is it, since statemtns 1., 2., and 3. show that each side of one triangle is congruent to a side of the other triangle. The proof used three sides congruent to three sides to prove the triangles congruent. That is the SSS thorem.
