Match the equation with the step needed to solve it. 1. 2m - 1 = 3m subtract 2 2. 2m = 1 + m subtract 1 3. m - 1 = 2 add 1 4. 2 + m = 3 subtract m 5. -2 + m = 1 add 2 6. 3 = 1 + m subtract 2m

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.
