Someone Please Help!!! Will give Brainliest!!!!!
Which of the following completes the proof?
Given: Segment AC is perpendicular to segment BD
Prove: ΔACB ~ ΔECD
Reflect ΔECD over segment AC. This establishes that ________. Then, translate point E' to point A. This establishes that ________. Therefore, ΔACB ~ ΔECD by the AA similarity postulate.
A.∠ABC ≅ ∠E'D'C'; ∠E'D'C' ≅ ∠ABC
B.∠ACB ≅ ∠E'C'D'; ∠D'E'C' ≅ ∠BAC
C.∠ACB ≅ ∠E'C'D'; ∠E'D'C' ≅ ∠ABC
D.∠ABC ≅ ∠E'D'C'; ∠D'E'C' ≅ ∠BAC
