The purpose of this website is to share some interactive GeoGebra applets that illustrate mathematical concepts. I hope that you find them to be useful and enjoyable.

GeoGebra is a free, open-source software package for dynamic geometry. It is an excellent alternative to proprietary systems such as Geometer's Sketchpad and Cabri Geometry. Since it is based on Java, it can run on almost any platform.
