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 terminology is consistent in the field of geometry, where the number of sides in polygons is often indicated by specific prefixes.

For example, other polygons include a triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), and hexagon (6 sides). When identifying the number of sides in geometric shapes, understanding these prefixes can help in easily recognizing them. Thus, knowing that "dodeca-" indicates twelve leads directly to the conclusion that a dodecagon has twelve sides.
