Does the orientation change in quadrilateral ABCD to A'B'C'D'? when reflected?
A.)Yes, and it is reflected over the x-axis
B.) yes , and it is reflected over the y-axis

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.
