Question

Which reason justifies the last step in a proof that ∆DEF ≅ ∆DAB?

Given: Line AD≅ Line ED, D is the midpoint of Line BF.

A. CPCTC
B. ASA Postulate
C. SAS Postulate
D.AAS Theorem

Answer 1

Hey there, Sheriawilright!

The correct answer should be C since we are given two sides AD is congruent to ED and D is the midpoint of Line BF meaning that BD and BF are the same. Also, it makes both lines make a vertical angle meaning they are the same. So we have two sides and an angle between, so the answer is Side Angle Side.
