These pages were created as part of a project to develop some interactive geometry material originally available in ATM magazine Micromath, for the ATM website at www.atm.org.uk. To understand what they are about, you should refer to the magazine. The first page you view will take a while to load up, but after that pages load quickly.

JavaSketchpad

Almost all the pages use JavaSketchpad. JavaSketchpad is the World-Wide-Web component of The Geometer's Sketchpad. Copyright ©1990-1998 by Key Curriculum Press, Inc.

Two pages use Cinderella interactive geometry. for more details go to their website at Cinderella.
