Ami and Dan are going to bake a cake. They need two and a half cups of flour. Ami has 5/4 cups of flour, and Dan has 4/3 cups of flour. Do they have enough flour to bake the cake? *

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.
