  Triskaidecagon Information
In Geometry, a triskaidecagon is a polygon with 13 sides and angles.
The measure of each internal angle of a regular triskaidecagon is approximately 152.308 degrees, and the area with side length a is given by
A regular triskaidecagon is not constructible with compass and straightedge.

Another interesting project would be to study Gleason's paper on a variation of Gauss' theorem.
Gauss showed the regular 13-gon (``triskaidecagon'') cannot be constructed by straight edge and compass.

 [No title]
As an introduction, the author describes a simple construction of the regular 7-gon (heptagon) which besides ruler and compass only requires the trisection of an angle and which is related to an older construction of J. Plemelj [Monatsh.
The main goal of the paper is the answer to the question: which regular polygons can be constructed with the aid of ruler, compass and angle trisector?
An application of this result is the construction of the regular 13-gon (triskaidecagon), which requires one angle trisection.

 People: hard to determine a rule with only three named polygons.
If you intend to skip one, the answer would be enneagon (however, the proper term for a 9 sided figure is nonagon).
There's no reason to choose dodecahedron (twelve), triskaidecagon (not a word, but I assume you used the Greek root triskaideka, thirteen), or icosahedron (twenty) given your beginning series.
If you intended to use etymologies all from one language or the other, then there's another problem: Square comes ultimately from the Latin (quadrum), where as Hex- and Hept- are from Greek roots.

 Actual electrostatics question - SciForums.com
If 13 stationary source charges are placed at the vertices of a 13-sided polygon (a triskaidecagon), what is the total electric field provided by them at the geometric center of the triskaidecagon?
I have a numeric/symbolic answer but I'd like to see someone solve it to see if our results are the same, especially since explaining my way would involve appeals to geometric ideas I can't convey in ascii.
I'd like to see if anyone can replicate.

 The Vicious Circle - by Matt Bronleewe >> Infuze Magazine   (Site not responding. Last check: 2007-10-28)
The next meeting of the Vicious Circle met in an inner sanctum of MoMA, home to some of the most beloved specimens of creativity in the world.
The chairs -- which numbered thirteen -- were again set in-the-round, though B.Z. Quain, the group's resident fictional-science-as-social-commentary writer, reminded them it was actually a triskaidecagon.
The taxi bolted from its position, causing both men in the back seat to grab at the handles above the door.
