Question

Given: AB = CD and BC = AD.
Prove: AB l| CD and BC || AD.

I need the reasons and the statements!!

Answer 1

Step-by-step explanation:

AC = AC by reflexive

∆ABC = ∆CDA by SSS

Angle CAD = angle ACB by CPCTC

Since alt interior angles are congruent, BC //AD

Repeat the same process to show AB//CD
