![]() (As far as I know, hexagons are the only regular polytope of any dimension with this particular property.) Hexagons are the only regular polygon that can be subdivided into another regular polygon.The hexagonal tessellation is combinatorially identical to the close packing of circles on a plane.Hexagons are one of only three regular polygons to tessellate the Euclidean plane (along with squares and triangles).At first glance, several facts about them stand out: The properties of hexagons are numerous and interesting. It has six rotational symmetries and six reflection symmetries, making up the dihedral group D 6. A regular hexagon is a convex figure with sides of the same length, and internal angles of 120 degrees. When describing things as "hexagonal" I am often referring in a very broad sense to all hexagonal and hexagon-like symmetries, and not necessarily to regular hexagons per se.Ī hexagon is a closed plane figure with six edges and six vertices. In addition, I tend to speak rather loosely about "hexagonal" this and that. ![]() Bear in mind that only a very small fraction of the interesting properties of hexagons are explored in this article, and it is hoped that a more complete view of their qualities will emerge through the sum of diverse material available on this site.Ī note about terminology: As is my general custom, and unless otherwise noted, "hexagon" refers to regular hexagons only. I intend to replace or at least supplement it with a more comprehensive and eloquent survey of hexagonal concepts at some point. ![]() This article is very much a work in progress, and is not really "done" in any meaningful sense. I have avoided discussing hexagons as they pertain to human culture, religion, history, and other "local" concerns, though there are many fascinating instances of hexagonality and sixness in these areas, and they will no doubt be treated more fully elsewhere at another time. My specific concern here is with the mathematical properties of hexagons, and, to an extent, their role in the natural world. ![]() It is not intended to be a comprehensive treatment of the subject. The following is a brief survey of some elemental properties of hexagons, and why they might be useful. ![]()
