Does this set of ordered pairs represent a function? Why or why not? (-5-5-1-20-2017) (9) O A Yes, because there are two values that are the same 3. No, because one value corresponds to two different y values O c. No, because two of the y values are the same D. Yes, because every value corresponds to exactly one y value​

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.
