How many sides does a hexagon have?

A hexagon is defined as a polygon with six sides. The prefix "hex-" comes from the Greek word for six, which clearly identifies the number of sides it possesses. In geometry, a hexagon can be regular, meaning all its sides and angles are equal, or irregular, where the sides and angles can vary. Understanding this definition and the characteristics of a hexagon is fundamental in geometry, making the answer that states it has six sides the correct choice.
