The sum of 3 consecutive even integers is 45. which equation represents this? a. (x) + (×) + (x) = 45 b. (x) + (x+1) + (x+2) = 42 c. (x) + (x+12 + (x+4) = 42 d. (x) + (x+1) + (x+3) = 42 ( show step by step)

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.
