Consider the function f(x) = -√x . Which list contains three points that lie on the graph of the function? O (1, - 1), (4, - 2), (9, - 3); (1, 1), (4, 2), (9, 3); (- 1, - 1), (- 4, - 2), (- 9, - 3); (- 1, 1), (- 4, 2), (- 9, 3)

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.
