How many sides does a dodecagon have?

A dodecagon is defined as a polygon with twelve sides. The prefix "dodeca-" originates from Greek, meaning twelve. This is a standard geometric term used in mathematics to describe shapes, and is consistent in various contexts involving polygons.

The distinction of a dodecagon can be seen in its characteristics, such as having twelve angles and vertices, which are fundamental properties of any polygon. Given the nature of the question, knowing the prefix is crucial in identifying the correct number of sides. Understanding the basic terminology of polygons is essential for recognizing and differentiating between them.
