Abstract
The article considers methods of construction of the locus of points in the learning environment of a new generation of GeoGebra used for the visualization of mathematical objects and the creation of their dynamic models. In other words, we are talking about the tasks of the following type. Let there be point A, which can move on a given curve L and the position of some other point B, rigidly connected with the position of the point A. Required to construct the trajectory that is described by the point B when moving A along the curve L. This trajectory and is called the locus of the point. We emphasize that the locus is not the equation of a line, but only a dynamic graph, although in some cases it can be used to find the equation. The connection between points A and B can be specified from both an analytical and a description that in some way can be found position B.
