JavaSketchpad Gallery

JavaSketchpad is a component of The Geometer's Sketchpad that allows you to export dynamic sketches you've created in Sketchpad as standalone applets on the Internet. These pages demonstrate various basic JavaSketchpad capabilities. For more ambitious uses of JavaSketchpad, visit some of the sites listed in JavaSketchpad Links.

Sorry, this page requires a Java-compatible web browser. If you're using a recent version of your browser, be sure to check its Preferences or Options to make sure that Java content is enabled. Attention: This page contains several JavaSketches. If this is the first JavaSketch you've encountered since starting your browser, it may take a few moments to load. (Look for an illustration to appear at the left.) You can also try refreshing your browser window. After loading the first JavaSketch, your browser will be able to load subsequent JavaSketches and pages much quicker. Please be patient.

Once the illustration appears, you can interact with it by dragging the red points.
