Compare each set of data. Determine which set shows greater variability.

Set A

5, 8, 9, 10, 12, 15, 16, 20

Set B

24, 34, 37, 42, 56, 57, 65

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.
