Tridecagon - Wikipedia
In geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon. A regular tridecagon is represented by Schläfli symbol {13}. The measure of each internal angle of a regular tridecagon is approximately 152.308 degrees, and the area with side length a is given by.
List of polygons - Wikipedia
In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain. These segments are called its edges or sides, and the points where two of the edges meet are the polygon's vertices (singular: vertex) or …
Name of Geometric Shapes - Polygons, Polyhedron - Online N-Sided …
Polygons are geometric figures of the 2D plane made up of a series of closed segments. The number of segments (called sides or edges) is equal to the number of vertices (or corners) used to define the geometric shape of the polygon.
Names of the Polygons - University of Regina
There seems to be an "official"set of names for polygons, uniformly derived from the Greek (after 4 sides). After about 6 sides mathematicians usually refer to these polygons as n-gons. So your 13 sided polygon I would call a 13-gon. To return to …
