Perpendicular Bisector Theorem

Dawn Wolf
Perpendicular Bisector Theorem: 1. Using the measurement tool, prove that line b intersects segment AB at its midpoint. What is line b called? 2. Choose three points on line b and verify they are equidistant from Point A and Point B. Summarize your findings. 3. Does the Perpendicular Bisector Theorem hold true for points below segment AB? Support your position.
Given line b is a perpendicular bisector of segment AB, prove the Perpendicular Bisector Theorem.
