Question content area top Part 1 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 aligned. Why is the distance from E to B the length of the new bridge? Question content area bottom Part 1 It is given that ▼ BC overbar congruent BE overbar . AB overbar congruent BD overbar . AC overbar congruent DE overbar . ▼ because they are vertical angles. ▼ angle ABC congruent angle DBE angle Upper A congruent angle Upper D because they are alternate interior angles. Therefore, triangle symbolBAC is congruent to triangle symbolBDE by ▼ So, CB overbar congruent BE overbar 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.
