Given: ae β
ce ; de β
be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that β³aeb β
β³ced, we can show that β³ β
β³ceb by. so, β cad β
β by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
