Which set of points lies on the given graph? A (3,9). (1-5), (3, 31
B (-3.9). (-1. 5), (3. -3)
C (3.9).(-1,5). (3. -3)
D (-3.9), (-1. 5). (3.3)

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.
