A dodecagon is a two-dimensional shape with 12 sides. A regular-shaped dodecagon has all its sides with the same length, and all internal angles are the same size. An irregular-shaped dodecagon has sides and angles of different sizes.
Know MoreA dodecagon also has 12 vertices and 12 internal angles at each one of those vertices. The internal angle in a regular dodecagon is 150 degrees, making the total sum of angles 1,800 degrees. Many historic buildings have been built in the shape of a dodecagon, including the Vera Cruz church in Segovia, Spain, and the Torre del Oro, a 13th century military watchtower in Seville, Spain.
Learn more about ShapesA 12-sided polygon is called a dodecagon. A polygon is any closed figure with 3 or more sides and angles. Every polygon with 3 to 20 sides has a name. Polygons with 30, 40, 50, 60, 70, 80, 90, and 100 sides have specific names as well.
Full Answer >A regular shape, also known as a regular polygon, is a shape that has sides that are all equal. If there are sides of differing lengths, these shapes are known as irregular polygons.
Full Answer >The dodecagon is the name of a 12-sided shape. This polygon also has 12 interior angles and 12 vertices. The sum of the interior angles of the dodecagon is 1,800 degrees.
Full Answer >A 12-sided two-dimensional polygon is called a dodecagon. A regular dodecagon has 12 sides that are all the exact same length and internal angles that are 150 degrees each. Since there are 12 internal angles, the total internal angles add up to 1,800 degrees.
