Use elimination method to solve the system of equations choose the correct ordered pairs 3x-4=-30 3x+2y=6 a.(0,3) b(-2,8) c(-2,6) d(0,4)

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.
