Ameatloaf recipe calls for 7/8 cups of breadcrumbs for the loaf and the topping if 3/4 cup is used for the loaf what fraction of a cup is used for the topping

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.
