Mark’s garden is a rectangle that is meters long and meters wide. if mark decides to fence his garden, the total length of fencing material required would be meters. if he uses prebuilt fence sections that are 50 centimeters wide, he will need sections.

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.
