Triskaidecagon → Tridecagon – This is the only polygon whose article uses "kai" in the name. Since both the forms with and without "kai" are just as common, we should move this for consistency with tetradecagon, pentadecagon, etc. Double sharp (talk) 11:28, 13 April 2012 (UTC)

However, we'll break consistency with Triskaidekaphobia, and "Triskaideka" seems to be more correct in classical ancient Greek... AnonMoos (talk) 19:11, 13 April 2012 (UTC)

Appearntly there's tridecaphobia too. I can't say what's correct. Why do some use deka? Conway says that Kepler used the kai. Tom Ruen (talk) 23:57, 13 April 2012 (UTC)

"Deka" is probably an alternative form. Double sharp (talk) 13:44, 14 April 2012 (UTC)

• Support (subject to revision after further evidence); for consistency in the naming of similar articles.
  [Evidence added later:] The full text of current OED records only "triskaidekaphobia" for words beginning with "triskai-". It does not record "tridecagon" in full text, nor any words beginning with "trideka-" or "triscai-". Note: there is an inconsistency in transliteration if both "c" and "k" are used in the same word to render Greek kappa; this inclines me even more toward "tridecagon", but usage should decide the matter.

  • Professional mathematicians usually use "13-gon" anyway, as they do for most (if not all) polygons beyond enneagons and decagons. Double sharp (talk) 13:43, 14 April 2012 (UTC)

• Redirect to regular polygon as not notable. The only thing that there seems of any interest is its name! Wikipedia isn't a dictionary. Dmcq (talk) 14:17, 14 April 2012 (UTC)
  • I was thinking about this for a long time (although since the word "triskaidecagon" does not imply regularity, a redirect to polygon might be better). Currently, I think that the 12-gon should be the cut-off for polygon articles, with the 17-gon (and possibly the 257-gon and 65537-gon) allowed as a special exception due to its constructability. Special comments can be included in the table at Polygon; the Petrie polygons could be mentioned in the Petrie polygon article. Double sharp (talk) 14:30, 14 April 2012 (UTC)
    • Makes sense to me. What's special about a 13-gon? —Tamfang (talk) 23:27, 15 April 2012 (UTC)

Don't see any real need to merge. French Wikipedia has separate articles on all polygons up to 40 (fr:Modèle:Palette Polygones), so I don't see why we can't go up to 20. Also, if all the information on the separate polygons is included into the "Regular polygon" or "Polygon" article, then that article will be long and cluttered... AnonMoos (talk) 00:57, 15 April 2012 (UTC)

But those articles only consist of properties that can be found from the general formulas already covered in polygon and regular polygon. This information need not be merged; only information specific to the polygon in question (such as constructability) should be merged. Double sharp (talk) 02:34, 15 April 2012 (UTC)

Obviously, the general angle / perimeter / area formulas would not be worked out for each individual n-gon in a merged article; however, there's other miscellaneous info (such as star polygons etc.) now in the unmerged articles, and I don't think the merge process would be as simple as you imply, unless such information were to be thrown away... AnonMoos (talk) 03:07, 15 April 2012 (UTC)

Star polygons can be constructed from all n-gons. The true star polygons (not star figures) are simply those n/d-gons where n and d have no common factor. The Petrie polygons can be covered in the Petrie polygon article. Double sharp (talk) 03:11, 15 April 2012 (UTC)

I have opened a deletion discussion at Wikipedia:Articles for deletion/Chiliagon. Double sharp (talk) 03:14, 15 April 2012 (UTC)

• Comment someone should copy the definitions for all spellings to wiktionary. 70.24.248.211 (talk) 06:44, 15 April 2012 (UTC)
• Comment - "kai" is Greek for "and". The Greek for 13 is treis-kai-deka with tris-kai-deka given as a variant form in my 1924 Greek Lexicon. However, this concerns trhe origin of the word, not English usage. I nevertheless womnder whether the correct target (if a change is needed might not be trisdecagon. Peterkingiron (talk) 21:32, 15 April 2012 (UTC)

Peterkingiron -- Both treiskaideka and triskaideka (without hyphens) can occur for in ancient Greek for the number 13 standing alone, but in compound forms (e.g. triskaideketes "thirteen years old" etc.) only tris- occurs. Triskaidecagon is a compound... AnonMoos (talk) 07:33, 16 April 2012 (UTC)

A Google search reveals "trisdecagon" as much less used than "tridecagon". Double sharp (talk) 13:05, 16 April 2012 (UTC)

Construction

The video of the construction is much too fast. — Preceding unsigned comment added by 217.44.162.92 (talk) 07:40, 13 May 2015 (UTC)
