In the diagram below, C̅D̅ is parallel to B̅E. Point B lies on A̅C̅ and Point E lies on A̅D̅. Which statement about ΔABE and ΔACD is true?

• They are congruent because they have the same angle measurements and the same side lengths.

• They are similar because they have the same angle measurements.

• They are not congruent because they have different angle measurements.

• They are not similar because they have different side lengths.
