1. If quadrilateral ABCD is a trapezoid then the segments of the diagonal are proportional. Prove, using the definition of a trapezoid, that the shaded pair of triangles is similar and the segments of the diagonals are proportional. Be sure to state which triangles are similar using the appropriate corresponding vertices. Also, using the given measures of the segments of the diagonal, find the length of EB.
