High School Resource: Definition of a Locus by Math Open Reference

High School Resource

Definition of a Locus by Math Open Reference

This resource illustrates the concept of locus. The page shows a model of the plane populated with a large number of points on a grid. Those points equidistant from a point are highlighted forming a circle. The user can drag the point and drag the distance, showing the circle moving and changing size.

There is a description of the locus concept and links to other loci – a straight line and an ellipse.

The page can be enlarged to full screen size for use with a classroom projector. After use in the classroom, students can access it again from any web browser at home or in the library with no login required.
