The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function
h(t) = 300-1672. which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its
fall?

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.
