http://www.math.com/tables/geometry/polygons.htm WebA 12 sided shape is a polygon called a dodecagon. Basically, a dodecagon is a polygon made up of 12 sides, 12 angles, and 12 vertices. The name of this 12-sided shape comes from the Greek words ‘dodeka’ and ‘hedra’, that mean ‘twelve’ and ‘seat/base’. Dodecagons can be regular, which mean that all the interior angles and sides ...

WebPolygon Formulas. (N = # of sides and S = length from center to a corner) Area of a regular polygon = (1/2) N sin (360°/N) S 2. Sum of the interior angles of a polygon = (N - 2) x 180°. The number of diagonals in a polygon = 1/2 N (N-3) The number of triangles (when you draw all the diagonals from one vertex) in a polygon = (N - 2) Polygon Parts.
