Final answer:
The two triangles are similar and have equal side lengths. This can be proved by dilating one segment to create another segment of equal length. The fact that the triangles have equal side lengths can be used to prove that they have equal angles.
Step-by-step explanation:
The two triangles are similar. This can be proved because segment BE is created by dilating segment CD, which means that the triangles have equal side lengths. This fact can be used to prove the triangles have equal angles.
