Entertaining geometry

In this book, geometry appears before the reader not just a set of dry numbers and boring theories, but a fascinating journey into the world of space. According to Galileo, nature always speaks with a person the language of mathematics: the letters of this language are circles, triangles and other mathematical figures. In this regard, Yakov Perelman deliberately moved classes in geometry from the close walls of the school room to free air, to the forest, field, to the river, to the road, in order to give up in open air to ease computing without a textbook and tables. As in the book “Entertaining Mathematics”, the author provides a set of unusual experiments and non -standard tasks that he managed to find on the pages of the works of classical literature - L.N. Tolstoy, A.P. Chekhova, A.S. Pushkin and N.V. Gogol. The book is addressed to both adolescents and adults who decided to interest their children with accurate sciences
