Atruck traveled 205 miles in 3 1/2 hours. the distance is the product of the rate and the time. to the nearest tenth, what is the average speed of the delivery truck? enter your answer in the box.

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.
