Identify the solution of each equation from the list given.

1. h + 9 = 21; 10, 11, 12 2. 34 + p = 52; 18, 19, 20 3. 45 – k = 27; 17, 18, 19

4. y – 13 = 24; 37, 38, 39 5. 28 = r – 12; 40, 41, 42 6. 56 = 7q; 7, 8, 9

7. 9w = 45; 3, 4, 5 8. 30 ÷ w = 5; 4, 5, 6 9. t ÷ 6 = 9; 52, 53, 54

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.
