Abstract
Abstract and teaching basic principles of the distinctive features of using the GeoGebra application when calculating a plot of flat shapes are revised in the article. Demonstrating the latest and also unique configurations, methods and methods of the concept of the training used material together with the target of attracting students of the 9th grade to the discipline geometry, increasing the productivity of mastering the training used material in addition, the current software provision has mainly changed the property of geometry lessons. Currently, it is difficult to imagine training in the absence of dialog modifications. One of the factors according to which it is difficult to master planimetry as well as stereometry is that the discipline is abstract. In the experimental work, it is presented that one of the methods of visualization of arithmetic, implementation in its movement is considered to be the use of the GeoGebra computer sphere. For this reason, in order to increase the interest and interest of students in arithmetic, along with the use of the latest technologies when conducting experimental activities, a GeoGebra software supplement was introduced into the lesson. In the process of studying, students were interviewed about the performance of GeoGebra projects. According to the results of the sample survey, it turned out that according to the results of the questionnaire, the students were able to realize and implement the tasks in absolute terms, introducing into their interest in geometry, independent selection, service along with additional literature, as well as basic skills according to programming. According to the results of the studies, it was presented that the use of the GeoGebra supplement in the calculation of the section of thin persons in geometry tasks is productive.
