Entertaining Geometry

Yakob Perelman proves that geometry is not at all a "cabinet" science created to torment students. In each section of this book, problems and stories are collected that will help not only to easily memorize complex formulas but also to... apply them in practice.
Perelman discusses not only well-known theorems but also practical everyday questions. How to measure the circumference of a glass without a ruler and a centimeter or count how many stars are reflected on the surface of a river? Why do wooden barrels have convex sides?
You will start to enjoy science and notice the laws of geometry everywhere: on the street, at home — and even in literature! In "Entertaining Geometry," for example, it tells about the geometric mistakes made in their books by Swift and Pushkin.
The book will be interesting not only to children but also to adults, and illustrations and diagrams will help to better understand and absorb the material.
