Hexagon partitioned into six equilateral triangles. Like squares and equilateral triangles, regular hexagons fit together without any gaps to "tile the plane" (three hexagons meeting at every vertex), and so are useful for constructing tessellations. The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials. The Voronoi diagram of a regular triangular lattice is the honeycomb tessellation of hexagons. It is not usually considered a triambus, although it is equilateral. The maximal diameter (which corresponds to the long diagonal of the hexagon), "D", is twice the maximal radius
Hexagon (comedy show) selected each year. Recent recipients have included Sarah's Circle, the ALS Association, Hospice Caring, and the Wounded Warrior Project. Hexagon is supported by the affiliated Friends of Hexagon. As of 2014, Hexagon had raised over $3.5 million for charity. Hexagon has received recognition for its work in the Washington community. In 1987, President Ronald Reagan presented Hexagon with the President's Volunteer Action Award for service. In 1993, "Washingtonian" magazine selected Hexagon as "Washingtonian of the Year," the first time an organization was named as the award's recipient. In 1994, the Greater Washington Area Chapter of Hadassah honored Hexagon with its
