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.

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.

[Free Registration/Login may be required to access all resource tools.] Apply perpendicular bisector properties.

[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.

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...

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

A list of geometry definitions and a matching activity.

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

Given a circle, students will construct a diameter of the circle. They will use the following theorem: In the same circle, if one chord is a perpendicular bisector of another chord, then the first chord is a diameter.

This activity uses Cabri Jr. to assess the students' knowledge of various segments related to triangles: perpendicular bisector, median, angle bisector, midsegment, and altitude.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to calculate midpoints and use the definitions of segment bisectors and perpendicular bisectors.
