## Requested move

The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

By far most assumed meaning, and the basis for most other uses of square. Square is currently only a redirect. Unlikely anyone would be surprised to find this page at Square. ~ JohnnyMrNinja 23:32, 24 July 2007 (UTC)

• Support - Everything else on the DAB page has an appendage. Reginmund 19:27, 25 July 2007 (UTC)
• Support -- I've just cleaned up the disambiguation page as it had turned into a list of every article with the word "square" in the name, which of course shouldn't be included in dab pages according to WP:MOSDAB and Wikipedia:Disambiguation#Lists. It still needs more cleanup though. Saikokira 19:48, 25 July 2007 (UTC)
• Support - it works for Cube, ought to work for Square. Tom Ruen 20:22, 25 July 2007 (UTC)
• Support: That is the primary meaning of square. Chris! my talk 22:01, 25 July 2007 (UTC)
Comment - I have just made similar proposals at Line (mathematics) and Plane (mathematics) ~ JohnnyMrNinja 01:26, 26 July 2007 (UTC)
• Oppose. Why not have square be a WP:DAB page, as per normal? — SMcCandlish [talk] [cont] ‹(-¿-)› 22:45, 25 July 2007 (UTC)
• Oppose. Square should either be or point to the disambiguation page. Even within mathematics, square (algebra), while originally derived from the concept of a square number, now has a far richer meaning, and is possibly even more prevalent than the geometric sense. Also note that pointing the redirect at square to square (geometry) rather then to the disambiguation page as previously has broken several hatnotes in related articles. Andrewa 14:55, 26 July 2007 (UTC)
• How do the meanings of cube differ from square? Cube is the geometry article with a note on top. If we're consistent, perhaps instead we should move the geometry to Cube (geometry) and redirect cube to Cube (disambiguation)? Just as a comparison but my vote is that primary noun usage should win, like as done with cube. Tom Ruen 17:20, 26 July 2007 (UTC)
• Agree that if this move is rejected, it would be good to look at cube as well, because many of the same arguments will apply. Cube (algebra) probably isn't quite as prominent a use of the term cube as square (algebra) is of the term square, in fact this usage of cube is in some ways derivative of the use of square in algebra. But a good point. Andrewa 01:18, 27 July 2007 (UTC)
• So far as consistency goes, we might also watch the similar requested moves concerning line and plane, both of which are attracting a good deal of opposition. Andrewa 01:26, 27 July 2007 (UTC)
• Oppose. The request is based on wrong assertions. “Square (mathematics)” matches a marginal meaning of the word “square”. --Juiced lemon 08:54, 27 July 2007 (UTC)
• Oppose a public square isn't necessarily square, or even a quadrilateral. SquareEnix is a common enough reference (formerly Square or SquareSoft). square as slang for unhip or squaring a deal etc, isn't related to the mathematical term, etc. 132.205.44.5 19:13, 27 July 2007 (UTC)
This opposition line is getting long. While we're dissenting common sense, let's make people click twice for a geometric pentagon too, just in case they mean something else. Tom Ruen 19:33, 27 July 2007 (UTC)
Good question. My first reaction is that pentagon still has a clear primary meaning, unlike square. There's a spectrum here, with one extreme being pentagon, square somewhere in the middle, and the other extreme probably being plane. The name of a plane (carpentry) may well derive from its use to make things flat (=planar; same word root), but it's a stretch to say that a carpenter means something to flatten things when they say plane, see rebate plane for example. English evolves, and we don't seek to promote any particular direction here. We use it as it is now, warts and all.
There are some subtle issues here, and they need to be raised, and even re-examined from time to time. Please don't take it personally if not all of your suggestions are adopted. For me, more than half of the reward of Wikipedia is when I do change my mind... it's objective evidence that I have learned something. See Talk:The Black Isle#Requested move for an example. Wikipedia also changes with time... (sigh) I put a lot of work into what I thought were legitimate fair use images years ago, and they even got some praise from other contributors at the time. Now they all look like being deleted! Andrewa 22:21, 27 July 2007 (UTC)
The above discussion is preserved as an archive of the proposal. Please do not modify it. Subsequent comments should be made in a new section on this talk page. No further edits should be made to this section.

It was requested that this article be renamed but there was no consensus for it be moved. --Stemonitis 08:34, 30 July 2007 (UTC)

## Square as infinite limit

Using the Cartesian coordinate system it can be expressed as:

${\displaystyle \lim _{n\to \infty }(~x^{2n}+y^{2n})=\lim _{n\to \infty }~a^{2n}}$

I removed this claim above, added recently, and edited into "even powers" now. I have some idea what it might mean, but it isn't referenced, and doesn't belong in the intro. If someone wants to draw some graphs or something to show the limit, might be interesting. As-is, I can't say it belongs in this article at all. Tom Ruen (talk) 23:01, 23 October 2008 (UTC)

Squircle and Superellipse discusses this shape. Showing that the limit defines a square is fairly easy, but alas no reference. --Salix (talk): 00:08, 24 October 2008 (UTC)

## congruent

It seems clearer to spell out "equal in length" rather than use the technical word "congruent" in a very basic article. Other objections to the concept of congruence of angles are discussed at Talk:angle and Talk:Congruence (geometry). Dbfirs 01:36, 4 March 2009 (UTC)

## Remove infobox?

It seems to me that the infobox on this page is unlikely to provide much helpful information for readers of this article. Would anyone mind if I were to remove it? Jim (talk) 22:45, 18 October 2009 (UTC)

Okay, I removed it. Jim (talk) 14:55, 21 October 2009 (UTC)
Sorry, I didn't see your original message. I restored the table. It's used by all the regular polygons and polyhedra and widely-crossed referenced. Tom Ruen (talk) 20:36, 21 October 2009 (UTC)

I wonder why nobody has already made a template for this in manner of general "overflows" of templates. I mean specially for non-English ones, when sometimes updates from English templates are hard(er) or behindhand with them. IMHO such information is concised, which is sometimes "helpful" (for visualizations), if for nothing. --xJaM (talk) 07:38, 23 July 2010 (UTC)

## (in)homogeneous square

Does anyone know what an homogeneous or rather an inhomogeneous square is? I know it exists and there is a geometric definition, but couldn't find an answer anywhere on the web. Harry2o (talk) 10:49, 16 March 2010 (UTC)

From a purely geometric point of view, I would have thought that any square has to be homogeneous if space is homogeneous, but the terms that you mention do seem to be used occasionally in other contexts. I think the definition depends on context, but perhaps an expert in lattice theory or informatics can give more detail. Dbfirs 02:12, 30 July 2010 (UTC)

## file

—Preceding unsigned comment added by 85.222.87.66 (talk) 22:37, 29 July 2010 (UTC)

I think these 2 values (in relation with the lenght of the square's side) should be presented here one after the another like they are presented in the equilateral triangle article. I posted the same request at the pentagon article (the regular pentagons category). Bigshotnews 06:18, 16 February 2011 (UTC)

Why and where does this article need additional citations for verification? What references does it need and how should they be added? Hyacinth (talk) 00:51, 29 October 2011 (UTC)

I've no idea. Some people ask for references for writing that grass is green. The facts can be checked in any standard text, but I suppose we can add a few general references if someone would be happier. I've added one. How many more do we need before we can remove the tag? Dbfirs 06:34, 29 October 2011 (UTC)
... years later ... There are seven citations, and four external links for verification, plus the facts can be checked in so many elementary text books. I think the "additional citations for verification" is too strong for an article that no-one has disputed. Is there a milder alternative? (I looked at one alternative, but the wording wasn't quite right.) Dbfirs 19:54, 6 April 2014 (UTC)

## Square perfect??

The vertical lines of the square in the infobox appear a little longer than the horizontal lines. Is this right?? Georgia guy (talk) 14:16, 22 January 2012 (UTC)

I think this depends on your display. They look equal in length on mine. Dbfirs 15:55, 22 January 2012 (UTC)
Have you rotated it so that it looks like a diamond?? Notice how a square looks like a diamond when rotated, but a nonsquare rectangle does not. Georgia guy (talk) 15:59, 22 January 2012 (UTC)
Yes, I tried rotating it and it still looks like a square or diamond, so I tried enlarging it to full screen and measuring carefully. On my screen, the shape is exactly square. Have you tried rotating the image (not the screen)? Dbfirs 17:44, 22 January 2012 (UTC)
Rotating the screen is the only way I know as for how to rotate it. Georgia guy (talk) 17:50, 22 January 2012 (UTC)
To check the squareness, I downloaded the image, rotated it 90 degrees using photo editing software, and superimposed the rotated shape on the original. They matched perfectly. Do circles on your display appear as ovals? Dbfirs 11:22, 23 January 2012 (UTC)
The circle article doesn't have an image of the kind I need; namely one with only the circumference shown. Georgia guy (talk) 13:42, 23 January 2012 (UTC)

## Picture for equation

I added the picture for the equation that I had proposed. However it messes with following parts of the article. I do not know how to fix this can somebody help? Alizter (talk) 21:24, 26 March 2013 (UTC)

Is that better? Chris857 (talk) 01:39, 27 March 2013 (UTC)

## squrring of number is also possible in anather technique

We know squring is multiplie No. with self No. or add No. with self times Their is anather method to squre the No that is add No with previous No and it's squre. Ex... We know 6th squre is 36 so 7th squre is 6+7+36=49.. Ex.. We know 25th squre is625 26th squre is 625+25+26=676.. Wecan use it as reverse Ex.. We know 7th squre 49 so 6th squre is 49-7-6= 36 We know 26 th squre is 676 so 25 squre is 676-26-25=625. Thanks anather mathes is also so comediaa. Easy & simple trieks.

Akshaykumar khairnar (talk) 09:32, 6 June 2016 (UTC)

Yes, this is a consequence of simple algebra: (n+1)^2 = n^2 + 2n + 1 = n^2 + n + (n+1). Dbfirs 12:47, 6 June 2016 (UTC)
