How many sides does a hexagon have?

A hexagon is defined as a polygon with six sides. The term "hexagon" itself comes from the Greek words "hexa," meaning six, and "gon," meaning angle or corner. This geometric shape can be regular, where all sides and angles are equal, or irregular, where side lengths and angles can vary, but it will always have a total of six sides.

Therefore, choosing the option that states that a hexagon has six sides accurately reflects this definition.
