This Demonstration shows a method of folding a strip to form a heptagon. This folding method is valid for regular polygons with an odd number of sides; the strip is made of a sequence of the largest trapezium whose legs are the sides of the polygon. For other than a regular heptagon (), only the first two steps are shown.
