Napoleon's theorem; theorem of Petr; polygon
Summary: Plane closed polygons are harmonically analysed, i.e., they are expressed in the form of the sum of fundamental \(k\)-regular polygons. From this point of view Napoleon's theorem and its generalization, the so-called Theorem of Petr, are studied. By means of Petr's theorem the fundamental polygons of an arbitrary polygon are found geometrically.
