Nthe graph above, the coordinates of the vertices of / are t(4, 4), u(2, –2), and v(6, –2). if / is reflected across the y-axis to create /, what are the coordinates of u'?

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.
