Summary
In addition to solving problems and examples in mathematics education, issues related to proof are also of special importance. Mathematical problems of proof encourage students to conduct research, including logical judgments, analysis and synthesis. The article provides general information about the concept of proof and shows the ways of proving issues related to the “Triangles” section, which is of great importance in the “geometry” content line.
