Denzel and three friends go to the movies. each person buys a movie ticket for $8, a snack for $4, and a drink for $2. which numerical expression represents the total cost of the trip to the movies for denzel and his friends?

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.
