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 - 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 | 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 Calculator - Regular 12-Side Polygon Properties Use this dodecagon calculator to find the area, perimeter, apothem, circumradius, interior and exterior angles, and the five diagonal lengths of any regular 12-sided polygon from one side length
Dodecagon Calculator | Try To 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
List of polygons - Wikipedia Individual polygons are named (and sometimes classified) according to the number of sides, combining a Greek -derived numerical prefix with the suffix -gon, e g pentagon, dodecagon
