C.a.R. is a software to simulate geometric constructions on a computer. This dynamic geometry means that constructions can easily be changed by dragging one of the primary points. During these changes, the constructions is repainted immediately. Moreover, tracks of points can be drawn.
Things you can do with the computer but not with the real thing are
The main user will be a school teacher, or a school class.
The program also teaches general principle of computer usage, since it sticks to widely spread interface techniques.
This version of C.a.R. is written in Java (© Registered Trade Mark by Sun). Java makes it possible to run the program in a browser, and to publish constructions and assignments in the Internet. It also makes it possible to use different operating systems.
