What is the primary property of a hexagon?

A hexagon is defined by having six sides. This is a fundamental attribute of its shape, directly indicated by the prefix "hex-" which comes from the Greek word for six. Hexagons can be regular, where all sides and angles are equal, or irregular, where sides and angles can vary. The property of having six sides distinguishes hexagons from other polygons, such as pentagons with five sides, heptagons with seven, and octagons with eight sides. Understanding this property is crucial when identifying and classifying geometric shapes.
