1. Module 14: Lesson 4 Perpendicular Lines
Perpendicular Bisector Theorem
If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
Then, AP = BP If P A B

2. Converse of the Perpendicular Bisector Theorem
If a point is equidistant from the endpoints of a segment, then that point lies on the perpendicular bisector of the segment.
Then, P is on the perpendicular bisector of the line segment. If
AP = BP P A B P B
