WITH AN EQUATION Marlen went to the mall and spent $35.75 on shoes. When she got home she had
$40.00 in her purse. Which equation can be used to find the amount of money she
started with?

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.
