are vertical angles, they have the same measure. Therefore, triangle . E A B. is similar to triangle . D C B. because the triangles have two pairs of congruent corresponding angles (angle-angle criterion for similarity of triangles). Since the triangles are similar, the corresponding sides are in the same proportion; thus the fraction . C D ...
