You are driving to visit a friend in another state who lives 440 miles away. you are driving 55 miles per hour and have already driven 275 miles. write and solve an equation to find how much longer in hours you must drive to reach your destination.

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.
