[edit] Cyclic quad

how do i prove that a quadrilateral is a cyclic quad - Anon

Good question. See cyclic polygon ... which isn't written yet. Wait and see :-) -- Tarquin 00:43 Aug 10, 2002 (PDT)

[edit] 3 dimensional and n dimensional

There should be reference to the superclass object that includes all other dimensional "rectangles". I couldn't find what this was but have always thought they were called Boxes. A page for Boxes or n-dimensional rectangles should be made, or if it exists, again should be referenced.

It's called a Cuboid or rectangular parallelepiped. I've added it to "See Also" Btyner 03:42, 29 November 2005 (UTC)

Few rectangles can be 8 x 4 = 32. What? Does this make any sense at all ? --anon

Yes, that sentence inserted by somebody did not make any sense. I removed it. Oleg Alexandrov 20:33, 27 September 2005 (UTC)

[edit] Oblong

I always thought an oblong was a rectangle standing on its shorter edge, so it's higher than it is wide. For example █ - that would be an oblong but the shape of most flags is not. I'm probably 100% wrong though —The preceding unsigned comment was added by Jodamu (talk • contribs) 15:25, 25 December 2006 (UTC).

. Yep, 100% wrong! :) I'm not sure about the relegation of the term oblong to a colloquiallism: an oblong rectangle is taught to be called an oblong (and a square rectangle a square) currently at UK primary school level. Rcrowdy

[edit] rectangle is fine, but what about rounded corners?

it is often useful to have shapes similar to rectangles, but with rounded corners.

but what are these called? the often used "rectangle with rounded corners" is self-contradictory, since a rectangle is defined a something with straight sides which intersect at right angles.

If you referred to it as a rounded oblong, that may make sense using the definition of an oblong as something longer than it is wide.

My friend from the Phillipines insists that an oblong is exactly that- a rectangle with rounded corners. In Australia we are taught that an oblong is a non-square rectangle. I think in common usage it may be fine to call a rectangle with rounded corners an oblong, but it is too ambiguous for mathematical usage.

[edit] Is a square a rectangle?

Mathematically speaking the properties of a rectangle make it the same as a square but when seen on paper they are different so is a square a rectangle or is it a different shape? I mean seriously people it is very interesting question the needs to be answered.

No a rectangle is part of the squares if Im not wrong. —Preceding unsigned comment added by 190.25.40.80 (talk) 23:38, 7 May 2008 (UTC)
