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.</p></abstract><trans-abstract xml:lang="ru"><p>В статье рассматриваются способы построения локуса точки в учебной среде нового поколения GeoGebra, используемой для визуализации математических объектов и создания их динамических моделей. Иными словами, речь идет о задачах следующего типа. Пусть имеется точка A, которая может перемещаться по некоторой заданной кривой L и позиция некоторой другой точки B, жестко связанной с позицией точки A. Требуется построить траекторию, которая описывается точкой B при перемещении A по кривой L1. Такую траекторию и называют локусом точки. Подчеркнем, что локус, не есть уравнение линии, а лишь ее динамический график, хотя в некоторых случаях его можно использовать для нахождения самого уравнения. Связь между точками A и B может быть задана как аналитически, так и описанием, по которому тем или иным способом может быть найдена позиция B.</p></trans-abstract><kwd-group xml:lang="en"><kwd>GeoGebra</kwd><kwd>GeoGebra</kwd><kwd>locus</kwd><kwd>dynamic model</kwd><kwd>triangle centers</kwd><kwd>and polar coordinates</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>локус</kwd><kwd>динамическая модель</kwd><kwd>треугольные центры</kwd><kwd>полярные координаты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Skrebnev Yu.M.
