 * If we approve this article, it definitely needs to be the lead article and have its image featured. Nyttend (talk) 22:09, 6 August 2012 (UTC)
 * Symbol question.svg This article looks like fun. I love math. I hope the sources aren't all offline or in another language. Pretty image is a bonus. Right off the bat though, there should be a minimum of one inline citation for each paragraph. Anne (talk) 21:42, 17 August 2012 (UTC)
 * Thanks for taking a look! I've . Many of the sources are behind paywalls, including the best secondary sources. Fortunately, you can always click on the Zbl link to view an abstract or a reviewer's summary, even for the Chinese articles, so that helps with verification. Also, every English citation with a URL attribute, which generates a link in the title, is free to access. Melchoir (talk) 23:17, 17 August 2012 (UTC)
 * Thank you. Anne (talk) 10:30, 21 August 2012 (UTC)
 * Date and length fine. Photo (nice job) licensed. Hook properly formatted and cited. Have started reading sources-it will be a while. Anne (talk) 13:59, 22 August 2012 (UTC) Running into a bit of a problem with sources. Most of the references are to sources that are either offline, abstracts, partial previews, or in another language. While sources don't have to be online, in this case, it makes it difficult to follow article. I think that some further explanation of terms would be useful. For example, in section 'Preliminaries': affinity, affine invariance, and affine-regular polygons. Anne (talk) 16:39, 22 August 2012 (UTC) For 'Best Results': need reference for "A conjecture by Stein (1990) proposes that no special polygon has an odd equidissection, where a special polygon is one whose equivalence classes of parallel edges each sum to the zero vector. Squares, centrally symmetric polygons, and polyominos are all special polygons."; also need links for equivalence classes and convex polygons; and definitions for n! and rational polygons.

 * Symbol question.svg My overall impression is that this is a well-written, thoroughly researched article. Suggestions as indicated above. Difficult to evaluate for copy vios due to accessibility of sources, but no copy vio issues noted with online sources. Others AGF. I note that the author didn't give citations for each paragraph, but instead in those instances gave author and date in the body of paragraph. That is acceptable to me (although I can't guarantee reaction of others). Topic, which at first glance seems relatively simple, is actually quite complex. To administrator: While I thoroughly reviewed this article, I wonder whether we have another mathematician other than Melchior who does DYK. While I was able to follow the math and principles in most paragraphs, I wasn't able to understand every single sentence. (While I love math, I chose a career in science/medicine.) I'm not certain that I've been able to do the article justice. Anne (talk) 20:32, 22 August 2012 (UTC)
 * Great feedback! I've addressed all the specifics with . Melchoir (talk) 01:41, 23 August 2012 (UTC)
 * Symbol confirmed.svg You're all set to go as far as I'm concerned, although it still might be nice to have a mathematician take a look (if we happen to have one other than you who does DYK). Very nice job! Anne (talk) 01:13, 25 August 2012 (UTC)
