Perpendicular Bisector Theorem

Activity Overview

This activity uses distance measures to investigate the relationship between a point in the plane and the distance to the endpoints of a segment. Students will investigate the implication these relationships have for the position of the point in the plane.

Before the Activity

Install the Cabri: Jr. App on the students' graphing calculators using TI-Connect™, a TI Connectivity Cable and the Unit-to-Unit Link Cable

Use the TI-Navigator™ to transfer the attached Cabri Jr. AppVar files to each calculator

See the attached PDF file for detailed instructions for this activity

Print pages 23 - 24 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Construct a segment, its perpendicular bisector, and a point not on the segment

Observe the relationship between the distance of the point from the endpoints of the segment, when the point is at various locations both on and off the perpendicular bisector

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
