C.a.R. is a dynamic geometry software effective, easy to use and very intuitive. Ideal for basic constructions in primary education and college, this software also makes it possible to build very complex geometrical figures.
Developed in Java by Rene Grothmann, professor of mathematics at the University of Eichstätt (Germany), this application is entirely free, multilingual and runs under mac OSX, Windows and Linux.
C.a.R. links
The officiel site : lot's of pages about C.a.R., with a documentation, demos and download links.

CaRMetal software site : it includes all of its functionalities - or almost - but follows a different approach from the graphical interface point of view. All the figures you can find on this server can be opened and made with C.a.R. or CaRMetal.
