Geometry for grade 7, ordinary and not very. Part 1

The twenty -second book of the series "School Mathematical Mugs" is devoted to geometry classes with schoolchildren of the 7th grade. It includes the development of eight classes of a mathematical circle with detailed examples of various complexity, tasks for independent solution and methodological instructions for the teacher.
A significant volume of the book occupies a list of additional tasks, their solutions and comments. The list of used literature is given, as well as the authors of the tasks. For ease of use, the final part of the book, as always, is made in the form of handouts.
The book is addressed to school teachers of mathematics and leaders of mathematical circles. We hope that it will be interesting to schoolchildren and their parents, students of pedagogical universities, as well as all lovers of elementary geometry
