Apair of equations is shown below.

x + y = 2
y = one halfx + 5

if the two equations are graphed, at what point do the lines representing the two equations intersect?

(4,-2)
(-2,4)
(2,5)
(5,-2)

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.
