Paula used a mirror to find the height of a telephone pole. she found her eye height to be 2 meters and 60 centimeters. her distance to the mirror was 1 meter 20 centimeters. the mirror was 15 meters from the telephone pole. find the height of the telephone pole.

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.
