Dodecagon - Wikipedia In geometry, a dodecagon, or 12-gon, is any twelve-sided polygon A regular dodecagon is a figure with sides of the same length and internal angles of the same size It has twelve lines of reflective symmetry and rotational symmetry of order 12
Dodecagon - Math. net A dodecagon is a 12-sided two-dimensional plane figure The term dodecagon is derived from Greek, where "dodeka" indicates 12 (do = two, deka = 10) and gon means angle or corner
Dodecagon Calculator A dodecagon is a polygon with twelve sides as well as twelve vertices and twelve internal angles This fact is encoded in the word itself, as dodeka is Greek for twelve
Dodecagon | Sides, Area, Angles (Example + Definition) Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which means angled Dodecagons can be regular, meaning all interior angles and sides are equal in measure
Dodecagon - from Wolfram MathWorld A dodecagon is a 12-sided polygon Several special types of dodecagons are illustrated above In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon
Dodecagon - math word definition - Math Open Reference To find the exterior angle of a regular dodecagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle See Exterior Angles of a Polygon Where S is the length of a side
