The article presents one of the types of tasks in the new workbook on geometry for grade 7 for the textbook by L. S. Atanasjan, et al. It is proposed to use visual diagrams for teaching conclusive reasoning. Various types of exercises are described, the basis of which is the technique of schematization, which promotes the student’s conscious mastery of the process of solving a proof problem. Techniques for developing self-organization skills when working with diagrams are also considered.
