Talk:Kite (geometry)

message: regarding the latest change, which is the former and which is the latter, it is unclear as you only mention kite flying in the sentence. Can you change it to "the geometric kite was inspired by the shape of the flying object" or whichever - I can't figureout which way it is. Onco_p53 11:09, 26 July 2005 (UTC)

replies: text: Deltoid is currently a disambiguation page pointing to both the muscle and the shape, as well as to a few other meanings. I don't think we should change that. —David Eppstein (talk) 00:13, 18 February 2009 (UTC)
replies: text: I have always defined "kite" to be convex, excluding the deltoid, dart, or arrowhead.  Does anyone actually use the term "concave kite"?  Should we modify the definition?  Dbfirs 08:31, 25 April 2009 (UTC)

message: Is there such a thing as a right kite? I mean, a right triangle reflected over its hypotenuse? What properties does it have?
:A right kite is a cyclic quadrilateral.—GraemeMcRaetalk 19:49, 24 June 2009 (UTC)
thread_title:  right kite 

message: : The kites are exactly the quadrilaterals that are both orthodiagonal and tangential. In a tangential quadrilateral, the two line segments connecting opposite points of tangency have equal length if and only if the quadrilateral is a kite.
If this is about tangency to an inscribed circle, that ought to be specified. —Tamfang (talk) 05:26, 12 January 2011 (UTC)

replies: text:  Yeah, belatedly (d'oh!). It would be more obvious if the paragraph break were removed. —Tamfang (talk) 05:39, 12 January 2011 (UTC)
replies: text: My idea of the structure here is that the first paragraph of the section describes properties related to the diagonals, the second paragraph describes paragraphs related to the inscribed circle, and the third synthesizes both of the previous paragraphs by combining the diagonals and the circle into a characterization of kites. But I don't mind if you want to restructure it. —David Eppstein (talk) 17:35, 13 January 2011 (UTC)

Some angles are quoted in degrees; some in radians. I prefer degrees. JDAWiseman (talk) 16:08, 9 September 2020 (UTC)

thread_title:  Aren't squares kites too? 

message: The word "diameter" appears three times in the article, in the context of "Among all quadrilaterals, the shape that has the greatest ratio of its perimeter to its diameter is an equidiagonal kite with angles 60°, 75°, 150°, 75°."
Diameter of what? The inscribed circle? If so, then this statement is false, because I can construct a kite with an unlimited ratio of perimeter to diameter (a really long pointy kite with a small circle inscribed).
Or is this restrocted to only equidiagonal kites? If so, then that isn't what the sentence says.
The article should clarify what "diameter" means here. Or clarify that sentence, both in the lead and in the body text. ~Anachronist (talk) 22:21, 11 August 2023 (UTC)
replies: text: Diameter here obviously means the largest distance between points (diameter = literally "measure across"). Your very pointy kite has ratio of perimeter to diameter of about 2, which is much smaller than the one described for which the corresponding ratio is >3 (for a square the ratio is 2\sqrt{2} \approx 2.83). The article gives sources in the relevant section later on. –jacobolus (t) 23:10, 11 August 2023 (UTC)

replies: text: That second definition is correct but more technical than necessary. The definition you quoted earlier, the largest distance between any two points, is simpler. —David Eppstein (talk) 02:00, 12 August 2023 (UTC)
