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. CPCTCB. ASA PostulateC. SAS PostulateD.AAS Theorem
Accepted Solution
A:
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.
