Carla and Jordan were trying to solve the equation: (x+1)(x-1)=8(x+1)(x−1)=8left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, minus, 1, right parenthesis, equals, 8 Carla said, "I'll multiply (x+1)(x-1)(x+1)(x−1)left parenthesis, x, plus, 1, right parenthesis, left parenthesis, x, minus, 1, right parenthesis and rewrite the equation as x^2-1=8x 2 −1=8x, squared, minus, 1, equals, 8. Then I'll add 111 both sides and take the square root." Jordan said, "The left-hand side is factored, so I'll use the zero product property." Whose solution strategy would work?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
