This movie shows all the regular polygons that can be exactly drawn using the instruments of classical geometry: ruler and compass. They are the polygons of 3, 4 and 5 sides, as well as their doubles (6, 8, 10), quadruple (12, 16, 20) and so on. Pentadecagons (15 sides) can also be drawn and, surprisingly, polygons of 17 and 51 sides. Read more details here:
