Original – The missing square puzzle is an optical illusion used in mathematics classes to help students reason about geometrical figures. It depicts two arrangements of shapes, each of which apparently forms a 13×5 right-angled triangle, but one of which has a 1×1 hole in it.

Reason: really clearly illustrates the puzzle, intriguing, and svg format.

Support I've certainly been shown this in a school maths class before. The raw svg rendering seems a bit dodgy in chrome unfortunately though. All rendered pngs look fine, and it looks fine at some sizes though, so I can't comment as to the cause and don't think its the file. JJ Harrison (talk) 09:16, 10 October 2011 (UTC)[reply]
- That is strange, it looks fine in IE and firefox, I'll double check with chrome when I get home... Aaadddaaammm (talk) 14:36, 10 October 2011 (UTC)[reply]
  - Looks fine in my Chrome. However, if I zoom the page, the image starts looking like the screen capture mentioned above. I also ran it through the W3C validator and it validates just fine. I zoomed a few other SVG images and they appeared to scale just fine. I don't know enough about SVG best practices to determine if something can be done differently in this image to prevent such a glitch. JBarta (talk) 17:59, 10 October 2011 (UTC)[reply]
    - Looks fine in my chrome, as far as I can zoom in. Aaadddaaammm (talk) 18:15, 10 October 2011 (UTC)[reply]
- Support, specifically the for png renders at the moment. FF7 on Debian here (for shame!); the SVG is not rendering perfectly -- the grid is misaligned with the pieces. EnkiduEnkita (talk) 01:39, 13 October 2011 (UTC)[reply]

Support: Looks okay to me. Got me to read the article to find the solution. Crisco 1492 (talk) 06:48, 12 October 2011 (UTC)[reply]
Support Same as the above - I'd seen this before yet still felt compelled to click through to the article. Nik thestoned 08:34, 13 October 2011 (UTC)[reply]
Support Had fun finding the solution. What a wonderful "game". Anyway, the thing is, this is pretty well done, and has EV, and presents in a very clear way the whole point. - Paolo Costa 20:23, 13 October 2011 (UTC)[reply]
