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

Students learn to draw a segment and its perpendicular bisector. They understand right angles and congruent segments. Students observe that changing the length or orientation of the segment changes the perpendicular bisector.

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.

Learn about the perpendicular bisector with this handy reference guide. Provides a detailed definition, examples, and an interactive activity that enhances further explanation.

In this activity, students use the drawing and measurement tools of Cabri Jr., to learn and understand the concept of "equidistant from the endpoints of a segment." They observe the changes if they move a point on the perpendicular...

Student activity: Discover that any point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment.

Learners explore the definitions and properties of the perpendicular bisector. The interactive activity includes an applet to explore the properties of the perpendicular bisector.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to construct perpendicular bisectors and use the Perpendicular Bisector Theorem.

Explains how to draw a perpendicular bisector and provides a definition of the perpendicular bisector theorem.

This activity uses Cabri Jr. to discover that the perpendicular of a chord passes through the centre of a circle. Microsoft Word documents are attached to support the lesson.

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...

Provides a definition and examples of perpendicular bisectors.

[Free Registration/Login Required] Students will move point N to the other points to determine when the line bisects the triangle perpendicularly. Click learn more to watch a video and click challenge me to answer practice questions.

This BBC Bitesize focuses on constructions and locus. To understand this activity, you must already know how to define perpendicular, bisect, and locus.

Students investigate the Perpendicular Bisector Theorem and examine its converse. They also explore the Angle Bisector Theorem.

The definition of isosceles triangle can determine whether an equilateral triangle is a special case of an isosceles triangle. Using the Cabri Jr. application, students can get a feel for which definition makes the most sense. Along the...

This study guide on lines and angles covers key terminology; line notation; parallel, perpendicular, and skew lines; and postulates and theorems about lines. It is available for download with free registration.

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

This site gives the proof that the three perpendicular bisectors of the sides of a triangle are concurrent.

Learn all about the point of concurrency. This lesson targets the point of concurrency of perpendicular bisectors, the point of concurrency of the angle bisectors of a triangle, and has interesting solved examples and practice questions.

A list of geometry definitions and a matching activity.

The goal of this task is to construct the circumcenter of a triangle, that is, the point which is the same distance from each of the triangle's three vertices. This task shows that the three perpendicular bisectors of the sides of a...
