The transformation of objects in GeoGebra

A. R. Esayan, N. N. Dobrovolsky

Tula State Pedagogical University

Abstract: The article provides an overview of the system GeoGebra is designed to perform various transformations of objects on the plane using built-in tools and commands. Transformations that can be implemented with tools and commands — a mirror image of the object relative to the direct (axial symmetry), reflection of an object about a point (сentral symmetry), inversion relative to the circle, rotate around a point, parallel to the migration on a vector, homothety relative to the point. In addition, with commands, Shear and Stretch, not having tools analogues, you can make variety shifts of objects along and across of directions.
Bibliography: 12 titles.

Keywords: GeoGebra, reflection, inversion, rotation, translation, homothety, shifts.
