Explaining The Universe on Instagram: "A dodecagon is a twelve-sided polygon. It has twelve edges and twelve vertices. In a regular dodecagon, all sides and angles are equal, with each interior angle measuring 150 degrees. The sum of all the interior angles in a dodecagon is 1,800 degrees, Dodecagons are often used in geometry, architecture, and design because of their symmetry and circular appearance when regular. They can also appear in engineering and mathematics problems involving rotational
