[Free Registration/Login may be required to access all resource tools.] Apply the definitions of midpoint, segment bisector, and angle bisector.

In this activity, students review definitions of terms such as right triangle, hypotenuse, midpoint, vertices, and equidistant. They also discover an important characteristic of the midpoint of the hypotenuse.

In this activity, students connect the midpoints of two sides of a triangle, to draw the midsegment of the triangle. They investigate how the length of this segment relates to the third side of the triangle. [Requires Adobe Reader.]

In this activity, students use the tools of Cabri Jr to test their knowledge of geometry. They investigate the properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral.

The Midpoint Formula finds the exact point that is halfway between two points. "Dr. Math" provides a formula that can be used to locate a point that is some fractional part of the entire segment.

[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.

A written proof that shows how the midpoint formula works.

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