CUT THE KNOT at

is an award winning site maintained by Alexander Bogomolny and contains delightful & stimulating geometry (& other) results. Most figures are interactive, and it also contains a forum for problem solving & mathematical results of interest.

ELEMENTARY TRIANGLE GEOMETRY at

Apart from algebra, trigonometry, statistics, etc. this site in the geometry section provides an exhaustive collection of simple to advanced geometry results related to the triangle, some trivial, some quite exotic. Downloadable in bookform, approx. 120 pp. (Also see

EUCLID'S ELEMENTS by David Joyce

GALLERY OF INTERACTIVE GEOMETRY at

Practice and play with interactive software for building rainbows, projective conics, and many more.

THE GEOMETRY CENTER at

The Center has a unified mathematics computing environment supporting math and

Computer science research, mathematical visualization, software development, application development, video animation production, and K—16 math education. A good place to start to find other links, ideas, and resources!

GEOMETRY IN MOTION at

JavaSketchpad sketches with exciting problems, investigations & articles.

GEOMETRY JUNKYARD at

DARIJ GRINBERG is a student whose homepage at

contains several unusual and new geometry results.

JAVASKETCHPAD GALLERY at

The sketch gallery of the JavaSketchpad web-site. Some sketches are designed to be manipulated interactively; some are in the form of "push-button" demonstrations, and some are self-running animations.
