Keisha, Dwayne, and Lonzell are planning for a new bridge to replace the old bridge. The new bridge will start at point B, where Dwayne is standing, and end at point C, where Keisha is standing. Lonzell walks to point D and then walks parallel to the river until he reaches point E where he sees Dwayne and Keisha are Old Bridge New Bridge aligned. Why is the distance from E to B the length of the new bridge? ..... It is given that because they are vertical angles. because they are alternate interior angles. Therefore, ABAC is congruent to ABDE by V So, CB BE because the corresponding parts of congruent triangles are congruent. This means that the distance from E to B is the length of the new bridge. 30 ft - 30 ft
