# HEXAGON

, in Geometry, a figure of six sides, and consequently of as many angles. When these are equal, it is a regular Hexagon.—The angles of a Hexagon are each equal to 120°, and its sides are each equal to the radius of its circumscribing circle. Hence a regular Hexagon is inscribed in a circle, by setting the radius off 6 times upon the periphery. And hence also, to describe a regular Hexagon upon a given line, describe an equilateral triangle upon it, the vertex of which will be the centre of the circumscribing circle.

The side of a Hexagon being *s,* its area will be .
