If line segment AC is the perpendicular bisector of segment BD, it means that point E is the midpoint of segment BD and that segment AC intersects BD at a right angle (90 degrees).
Given that E is the midpoint of segment BD, it follows that segments BE and DE are equal in length. Therefore, segment BE is half the length of segment BD.
To summarize:
- Segment BE is equal in length to segment DE.
- Segment BE is half the length of segment BD.
