Can there be geometry in the forest, in the open field, on the road, in the dark, on the set, in newspaper headlines and articles, where heaven and earth converge? It turns out it can! Geometric quantities and concepts can be found everywhere around us. These are planes and angles, distances and angles, simple and intricate geometric shapes. Some of them can be drawn with a single stroke, without taking the pen away from the paper. Perhaps the reader is already familiar with the expressions: 'the number of pi' and 'the quadrature of a circle'. And how and when did they arise, and how to calculate them? Yakov Perelman's book "Entertaining Geometry" will help to complement and diversify school knowledge with live examples, understandable explanations and unusual tasks.For middle school age.
