Radius of a Regular Polygon

Radius of a Regular Polygon should be added as a sub-section somewhere in this article. I'd add it myself, but I bet it would be more than likely removed for a reason that doesn't exist. 198.150.12.32 (talk) 16:21, 24 April 2008 (UTC)[reply]

Done. I also mentioned the distinction between the inradius and the circumradius. --68.0.124.33 (talk) 18:28, 2 October 2008 (UTC)[reply]

Vandalism

There's been a lot of vandalism latley. And it's been going on for two months. What should we do? Wuffyz (talk) 20:32, 14 May 2008 (UTC)[reply]

You can always request semiprotection at Wikipedia:Requests for page protection. That’s not always a pretty solution though, because then genuine edits are prevented from anonymous users as well. GromXXVII (talk) 21:40, 14 May 2008 (UTC)[reply]

I noticed that "The inradius of a regular polygon is also called apothegm." Apothegm seems to link to the wrong page. —Preceding unsigned comment added by 69.92.166.134 (talk) 05:46, 18 April 2010 (UTC)[reply]

Disambiguation

The article needs a disambiguation page so the following "Radius" also has an article under the same name.

Radius from three points

Should there not be a diagram which shows "a circle going through three points P1, P2, P3" as to show "where θ" "the angle" is? I am sure a young person reading this would be asking themselves where the vertex is. John W. Nicholson (talk) 11:54, 2 September 2012 (UTC)[reply]

Some history / etymology?

It would be nice to have some history (about the subject, not about the article!) for this article 20040302 (talk) 16:02, 12 November 2018 (UTC)[reply]
