The hexagon

In geometry,

hexagon (from Greek ἕξ hex, ‘six’) is a polygon with six edges and six vertices. A regular hexagon has Schläfli symbol {6}. The total of the internal angles of any hexagon is 720 degrees.


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 beehivehoneycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials.
