Question

Write an indirect proof to show that opposite sides of a parallelogram are congruent. Be sure to create and name the appropriate geometric figures.

Answer 1

So the problem ask to find an indirect proof to show that opposite sides of a parallelogram are congruent. So if we want to prove that a rectangle has a vertexes of ABCD where as to prove that AB=CD, lets start by proving it using AB is not equal to CD nad forming a parallelogram and the lines that bisect each side can prove that AB=CD
