Lessons in geometry through problems. 7th-8th grades

The book summarizes the author’s experience in teaching geometry in several Moscow schools. There are many drawings in it - this strongly saves time in the lessons. Each paragraph gives reference material - the formulation of the main theorems and definitions.
The material of each topic is built according to the classical principle: from simple to complex. The first tasks are available to every student, the latter reach the level of serious mathematical olympiads. About half of all the tasks are copyrighted. The selection for each topic is built in such a way as to show the method contained in it from all sides. This book is compiled precisely for work in the lessons, so there are no solutions in it, only answers.
The book is intended for schoolchildren, teachers of mathematics, students of pedagogical universities and universities.
