Last year’s cost, c , of a water park season pass increased 35%
. The expression c+0.35c
can be used to represent the increased price of a season pass. What is another expression that can be used to find the new cost of a season pass?

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.
