Clare used a compass to make a circle with radius the same length as segment AB. She labeled the center C. Which statement is true?

• $AB>CD$

• $AB=CD$

• $AB>CE$

• $AB=CE$

In the construction, A is the center of one circle, and B is the center of the other. Identify all segments that have the same length as AB.

• segment $AC$

• segment $AE$

• segment $BC$

• segment $CD$

• segment $DE$
