Geometry on moving drawings

The nineteenth book in the "School Math Clubs" series is devoted to solving geometric problems using dynamic geometry programs - "Geogebra", "Mathematical Constructor", "Living Mathematics".
After studying the book, the student will learn to work in a dynamic geometry program, build and study movable drawings, master the basic techniques of mathematical experiments in solving complex problems - putting forward, testing and clarifying hypotheses - and also repeat the main topics and ideas of the planimetry course.
The book is addressed to school mathematics teachers and leaders of mathematics clubs.
2nd edition, revised and expanded.
