AB  - The paper presents the characteristics of the most widely used software products with the common name "dynamic geometric systems" in Slovakia, which are designed to teach plane geometry in elementary and secondary schools, and colleges that prepare teachers of mathematics too. Attention is given to three programs: Cabri Geometry, Compass and Ruler and GeoGebra. The aim is to give some parameters in comparison of nominated programs that are crucial in selecting of the environment for a particular mathematical task and its implementation.
