be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that ā³aeb ā
ā³ced, we can show that ā³ ā
ā³ceb by. so, ā cad ā
ā by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
