An interactive applet and associated web page that demonstrate major and minor arcs. The applet shows a circle with two points on it that can be dragged. The minor and major arcs they define are shown in different colors which change places if dragging a point alters the relationship.

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