# given ad = bc prove a b

Anyway, I have to prove the distance of AC=BD, and without any numbers, I'm kind of lost. This is true even if a/b or c/d is already in lowest terms. Q: In the following 2-column proof, what is the missing statement to prove that ABS = CDB, by SSS. 1. By BeZout's identity: \$1=ar+(bc… C is the midpoint of BD Prove that Δ ABD Δ CBE.
