Abstract

Hexagonal systems are geometric objects obtained by arranging mutually congruent regular hexagons in the plane. Such geometric features are usually not considered in secondary-school courses of mathematics, although these are easy-to-grasp and probably interesting to students. In this paper the elements of the theory of hexagonal systems are outlined. We indicate some properties of hexagonal systems that secondary-school students could prove themselves, as well as a few less easy results and open problems.
