The hexagon is a six-sided polygon with straight sides and angles. It is a fundamental shape in geometry and is widely encountered in various natural and man-made objects, from crystals and honeycombs to architectural designs and industrial applications.
Geometry and Properties:
A regular hexagon has six equal sides and six equal angles, each measuring 120 degrees. The sum of its interior angles is 720 degrees, making it a convex polygon. The distance from the center of a regular hexagon to any of its vertices is called the circumradius, while the distance to its sides is known as the inradius.
Area and Perimeter:
The area of a regular hexagon can be calculated using different formulas, such as A=233×s2, where s represents the length of one side. The perimeter of a hexagon is the sum of its six sides, given by P=6s.
