Using of Geogebra in geometry lessons

Abstrakt

The article discusses the use of electronic educational resources as a means of computer support for teaching mathematics to train competent professionals in the field of "Secondary education. Maths". Attention is drawn to the need for quality training of educators able to use innovative methods and teaching aids with a focus on developing research competencies. The use of GeoGebra’s interactive geometric environment to visualize mathematics, conduct experiments and research in solving mathematical problems is explored. The possibilities of using GeoGebra for acquaintance, verification, anchoring and repetition of properties of geometric figures are considered. Examples of basic and alternative  сonstructions of a square, rectangle, parallelogram, equilateral and isosceles triangles, bisector of angle and median perpendicular of a segment, regular hexagon, centers of inscribed and described circles on the basis of their properties.
