The course of geometry is focused on the students` development of cognitive abilities. On the basis of experimental activities students themselves discover geometrical relationships, develop and consolidate their understanding of geometrical concepts.
Some polygons are introduced and studied in depth using the environment of grid paper. In addition the relationships between straight lines, line segments, angles, shapes for parallelism, perpendicularity, equality are studied as well as the isometric transformations in the plane and measurement of geometrical shapes.
New knowledge is studied in different environments.
