|It is very easy to download and use any GeoGebra activity embedded on any page.
- Download and install GeoGebra from http://geogebra.org.
- Then open the webpage with the GeoGebra interactivity you want.
- Double-click on the interactivity* (somewhere where it is blank so it doesn't just open an object). The file will open as a GeoGebra file in a separate window on your computer with all menus active.
- Choose File->Save from the main menu.
It is now on your computer and can be used directly and/or changed as you need.
Of course, if you embed it somewhere public, I am sure the author would appreciate acknowledgement.
