Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 4/5, a change of 1 unit in x corresponds to a change of 4/5 units in 1. 1. Graph the line.
The equation is.

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.
