Developer / company: R. Grothmann

C.a.R. is dynamic geometry program. Basically, it simulates compass and ruler constructions on a computer. But on a computer, much more is possible.

  • Ruler and compass constructions can be changed by dragging one of the basic construction points. The construction follows immediately. The student can check the correctness of the construction and gain new insight.

  • Tracks of points and animated constructions can help to understand geometric relations. Tracks can be used as new objects to explore.

  • With the macros of C.a.R. very complicated constructions become possible. Macros are also a way to organize the geometric thinking.

  • Hiding construction details and using colors make constructions clearer to read. In C.a.R. lines and circles can also be reduced to the relevant points.

  • Arithmetic computations, numerical solutions, curves and functions go beyond classical constructions. It is even possible to construct in 3D using advanced macros.

  • Other geometries, hyperbolic or elliptic, can be explored.

C.a.R. works on all modern platforms. Constructions and assignments can be embedded into web pages easily. C.a.R. has been translated in many languages.

C.a.R. can be used free of charge, and the source is available under the GPL license. Seems like old program and no longer available.

The C.A.R. software seems to be old or discontinued.
Such programs may not work on modern operating systems properly, are no longer available and supported by their original developers, or are simply obsolete for their purpose. Sometimes companies offer limited support through their website.

C.A.R. pictureC.A.R. works with the following file extensions:

Note: You can click on any file extension link from the list below, to view its detailed information. The list of extensions used or otherwise associated with the application may not be complete, because many common file extensions on our website, such as jpg (pictures) or txt (text files), can be opened by a large number of applications, or are too general file format. However most, if not all directly associated file extensions should be listed with its appropriate program. Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
