Instructions for the installation and use of Geometry Playground

Installation and Launch

To run Geometry Playground you will need Java 1.80 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 you may launch directly from the Playground.jar (e.g. "double-click").

Operating System Specifics

• Windows
• Mac
  • Another helpful tip will be to
    • "right click" on the Playground.jar file
    • Choose "Open With > JavaLauncher.app"
    • Verify that you want to open Playground.jar
      • May need administrative permissions
    • Once the above steps are complete, double-clicking will be sufficient.
• Linux

Alternatively, running the following command from a terminal prompt will do the same: java -jar Playground.jar.

Launch in Replit

Geometry Playground is hosted on an online serving environment with limited capacity. It should be sufficient to demonstrate the principles without installation.
