Tracks

Tracks are an important part of dynamic geometry. Tracks show the traces of points, when some construction parameter changes. To look at a track may lead to new discoveries. C.a.R. can also draw polar sets for a family of lines. Moreover, tracks can be animated.

C.a.R. supports two types of tracks. First of all, you can simply move one point and paint the track of another point, or even the tracks of several other points. Secondly, you can generate automatic tracks, where a point runs on a circle or a line. This type will generate all states of a construction, changing intersections and switching the direction of the moving point automatically as necessary. This type of track can be fixed in the construction and used like any other object, defining intersections and keeping points on it.
