What are the measures of the other three angles formed by the intersection?

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.

Which of the following is missing in the explicit formula for the compound interest geometric sequence below?

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?
