Entertaining Geometry

Can there be geometry in the forest, in an open field, on the road, in the dark, on a film set, in newspaper headlines and articles, where the sky meets the earth? It turns out there can be! Geometric quantities and concepts can be found all around us. These are planes and angles, distances and perspectives, simple and intricate geometric figures. Some of them can be drawn in one stroke, without lifting the pen from the paper. The expressions "pi" and "squaring the circle" may already be familiar to the reader. But how and when did they arise, and how can they be calculated? Yakov Perelman’s book "Entertaining Geometry" will help complement and diversify school knowledge with living examples, clear explanations, and unusual problems. For middle school age.
