# Lesson Plan: Perpendicular Bisector of a Line Segment Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the perpendicular bisector of a line segment by identifying its midpoint and finding the perpendicular line passing through that point.

#### Objectives

Students will be able to

• find the midpoint of a line segment given its endpoints,
• find the coordinates of an endpoint given the midpoint and the other endpoint,
• understand that the midpoint of a diameter of a circle is the center,
• find the equation of the perpendicular bisector to a line segment by identifying its midpoint and finding the perpendicular line passing through that point.

#### Prerequisites

Students should already be familiar with

• finding the distance between two points,
• equations of perpendicular lines.

#### Exclusions

Students will not cover

• equations of circles,
• intersections of circles and straight lines.
