Instructions
To run Geometry Playground you will need Java 1.50 or greater installed on your computer.
To download Geometry Playground follow this link to the Playground.jar file.
If the Playground.jar file is set to "executable" and associated with a Java Runtime Executable (see instructions for win, mac, linux) you may launch directly from the Playground.jar (e.g. "double-click").
