A and B are two distinct points in the plane and line AB is the segment joining them. The goal of this problem is to construct the perpendicular bisector of segment AB. Aligns with G-CO.D.12.

MathWorld's definition of a perpendicular bisector, with illustrations to show the different uses of the perpendicular bisector.

This site from Advogato is all about angles. It contains information starting with what an angle is and what it looks like, all the way up to bisecting angles and theorems about angles. This is very good information for students just...

This lesson defines midpoint and segment bisector, and provides examples that demonstrate how to distinguish between the two. It is 7 of 10 in the series titled "Midpoint vs. Segment Bisector."
