The book is devoted to geometric problems for construction and is intended for classes with schoolchildren in grades 7-9. It included the development of nine lessons of a mathematical circle with detailed examples of varying complexity, tasks for independent solution and methodological instructions for the teacher. There is also a large list of additional tasks. Most of the problems discussed in the book are classic for this section of geometry. The appendices contain historical information, as well as some issues of increased difficulty associated with geometric construction tasks.
