A dodecagon has 12 sides.
The term ‘dodecagon’ comes from the Greek words ‘dodeka’, meaning twelve, and ‘gonia’, meaning angle. Therefore, it’s a polygon with twelve angles and twelve corresponding sides. In geometry, dodecagons can be regular, where all sides and angles are equal, or irregular, where sides and/or angles are not equal. A regular dodecagon has internal angles of 150 degrees each. Understanding dodecagons can help in various areas, including architecture and design, where complex shapes are often utilized.
