About Regular Hexagons
A regular hexagon is a six-sided polygon where all sides are equal length and all interior angles are 120 degrees. It is one of the three regular polygons that tile the plane (along with the equilateral triangle and square).
The circumradius (distance from center to vertex) of a regular hexagon is exactly equal to the side length. This makes the hexagon unique among regular polygons. The inradius (apothem, distance from center to the midpoint of a side) is s*sqrt(3)/2.
A regular hexagon can be divided into exactly 6 equilateral triangles, which is why its area formula involves the equilateral triangle area. Hexagons appear everywhere in nature -- honeycombs, basalt columns, snowflake symmetry -- because they efficiently tile space with minimal perimeter.
The long diagonal passes through the center (vertex to opposite vertex) and equals 2s. The short diagonal connects non-opposite vertices and equals s*sqrt(3).
