After about 6 sides mathematicians usually refer to these polygons as n-gons. So your 13 sided polygon I would call a 13-gon. Cheers, Walter and Harley Go to Math Central. To return to the previous page use your browser's back button.


Polygons A polygon is a plane shape with straight sides. Is it a Polygon? Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).


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. The triangle, quadrilateral and nonagon are exceptions, although the regular forms trigon, tetragon, and enneagon are sometimes encountered as well.


A 13-sided polygon can either be called a triskaidecagon or a tridecagon. What shape is a thirteen sided polygon? The name of a 13 sided polygon is Tridecagon. share:

What are some names of polygons with more than 13 sides? Personally I like the hendecagon but alas it only has 11 sides. Oh well, here are some from Wikipedia: * Icosidigon (22) * Icositetragon (24) * Icosihexagon (26) * Icosioctagon (28) * Triaco...


A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square.


In geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon Regular tridecagon. 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 ...
