Duodecagon

A duodecagon is a polygon with twelve sides and twelve angles. Its internal angles sum up to 1800 degrees. Regular duodecagons, where all sides and angles are equal, can be constructed using a compass and straightedge. They possess rotational symmetry of order 12 and twelve lines of reflection symmetry. The name is derived from the Latin 'duodecim' (twelve) and 'gonia' (angle). Duodecagons are less common in everyday objects compared to other polygons, but they appear in architectural designs, as well as, sometimes, as the shape for some nuts and bolts or even stop signs.
