School mathematical clubs. Geometric problems on extrema

The next book of the series "School Mathematical Mugs" is devoted to geometry classes (namely geometric tasks for the maximum and minimum) with schoolchildren from 7 to 10 grade. It includes the development of nine classes of a mathematical circle with detailed examples of various complexity, tasks for independent solution and methodological instructions for the teacher.
A significant amount of book is 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
