If line segment \( AC \) is a perpendicular bisector of segment \( BD \) and they meet at point \( E \), then the following is true:
- By definition of a perpendicular bisector, it divides segment \( BD \) into two equal parts. Therefore, segment \( BE \) must be equal in length to segment \( ED \).
From the options provided, the one that best represents the relationship is:
It must be the same length as segment DE.
So the correct response would be:
It must be the same length as segment DE.
