Suppose that when your friend was​ born, your​ friend's parents deposited ​$8000 in an account paying ​3.2% interest compounded quarterly.. What will the account balance be after 16 ​years?

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.
