Наглядная геометрия_x000D_

The manual "Visual Geometry" is intended for middle school students. It allows for the study of geometry to begin in the 5th-6th grades, to eliminate gaps in geometry knowledge in the 7th-8th grades, and in senior classes to prepare for the GIA and USE.
The problems included in the manual are research-oriented and do not require knowledge of special formulas and theorems. They vary in difficulty, from simple to Olympiad-level, and are aimed at identifying mathematical abilities, developing geometric concepts, and constructive skills of students.
