A regular hexagon is a six-sided polygon where all sides and angles are equal. Each internal angle measures 120 degrees, and the shape can be perfectly inscribed in a circle, meaning all its vertices touch the circle's circumference. Regular hexagons are commonly found in nature, such as in the structure of honeycombs made by bees. The symmetry of regular hexagons allows them to tessellate, or fit together without gaps, making them useful in various designs and patterns. They are often seen in tiles, flooring, and even in games like board games that use hexagonal grids for movement.
