hel which expression is equivalent to –5x + 4. (-3x) + 3 + (-2x) + 1 (-3x) + 3 + (2x) + 1 3x + 3 + 2x + 1 (-3x) + (-3) + (-2x) + (-1)

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.
