"Like squares and equilateral triangles, regular hexagons fit together without any gaps to tile the plane (three hexagons meeting at every vertex), and so are useful for constructing tessellations." 
       Up to here it is ok, but see how it goes -->
"The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials."
I propose this second line goes away...  —Preceding unsigned comment added by Muazzes (talk • contribs) 12:26, 3 August 2008 (UTC)

message: I think we need a picture of a honeycomb to illustrate "hexagonal cells".
The Main Page currently mentions 
"the ideal cellular network has evenly distributed hexagonal cells"
-- but clicking on hexagonal just redirects to hexagon, which doesn't say anything about hexagonal cells (hexagonal arrays). It only talks about single hexagons.

message: Is "sexagon" really a good term?? I say no. "Hexagon" is completely Greek. "Sex" is a Latin prefix. If the word were Latin, it would be "sexangle". See Greek numerical prefixes and Latin numerical prefixes. 66.245.11.175 14:05, 15 Jun 2004 (UTC)
replies: text: I don't think I've ever heard it called a sexagon, though the equally mixed-up nonagon for enneagon is common, and I've also heard of septagon instead of heptagon.  So if the term's to be mentioned, I suppose it ought to have some wording discouraging its use.... -- Smjg 16:23, 18 Jun 2004 (UTC)

message: Is it true that a square whose sides each measure ten centimeters can completely fit inside of a regular hexagon whose sides each measure ten centimeters ?
:I don't think so. I'm no expert but I know that the area of such a square is 100 cm2, and I think the area of the hexagon is 150 \sqrt 3, which clearly isn't possible. However, I think there is some true theory involving a cube of 10 cm sides and a hexagonal hole with 10cm sides, but I don't know much about it. Maybe you could try the reference desk? Hyenaste (tell) 04:45, 28 August 2006 (UTC)
replies: text:  By my calculation, it's perfectly possible for the area of a regular hexagon of side 10 cm to be 150 \sqrt 3 cm2.  What do you mean exactly? -- Smjg 23:26, 29 August 2006 (UTC)
replies: text: I mean it is not possible for shape with an area of 150 \sqrt 3 cm2 to fit inside an area of 100cm2. Hyenaste (tell) 01:53, 30 August 2006 (UTC)
replies: text:  You've got it the wrong way round.  The rest of us are talking about a square of side 10cm, area 100cm2, fitting inside a hexagon of side 10cm, area 150 \sqrt 3 cm2.  Not of the hexagon fitting inside the square. -- Smjg 14:47, 16 September 2006 (UTC)
replies: text:  Yeah, I realise that now. I read his question, thought about the "hole-through-the-cube" I mentioned, and assumed he was asking a different question. Oh well. Hyenaste (tell) 23:03, 16 September 2006 (UTC)

text: Easily so, I would say. Imagine a hexagon with side length 10cm. Take one of those sides and draw a 10cm x 10cm square from it, inside the hexagon. The hexagon is much bigger. Tomid 15:05, 31 August 2006 (UTC)

text: I'm no geometrician, but I think you're confused about interior angles. The interior angles of a polygon do not have to equal 360°. If, like you suggested, each angle was compressed to 60°, the shape would become two equilateral triangles, the second a trace of the first. Hyenaste (tell) 23:03, 16 September 2006 (UTC)

text: I think you are describing the angle subtended at the centre by a side.  If so, then this is indeed 60 degrees for a regular hexagon.  For a regular n-gon, this angle is always 360 divided by n degrees.  Dbfirs 17:42, 2 May 2011 (UTC)

thread_title:  Pictures of Tesselations 

message: In the late 1970s, there was an article in Scientific American magazine about market dynamics in Imperial China in the Middle Ages.   The idea of using a hexagonal array of markets and sub-markets arises from the observation that the forces of supply and demand tend to oscillate, or alternate, much like a teeter totter rises and falls, and far from going out of balance, actually tends to arrange itself in a dynamic balance of sorts. 
The main article could be improved if there were a reference to the magazine article about market forces arranging themselves into hexagons.  216.99.201.35 (talk) 20:34, 19 June 2009 (UTC)

thread_title: Use of hexagons in construction

message: added this sentence to the Regular hexagon section:
: It is not usually considered a triambus, although it is equilateral.
I had not known the word triambus before.  The link to equilateral polygon implies that a triambus is any hexagon with equal sides; but the name suggests that alternately-equal angles are also a defining feature.  Which is it?
Let's have a new section about triambs. —Tamfang (talk) 18:39, 1 May 2011 (UTC)
replies: text: I can't find much about them except for thisthat suggests just normal equilateral hexagons.  Neither Wiktionary nor the big Oxford English Dictionary defines any of "triamb", "triambus" and "triambic".  Are they notable enough to mention, and, if so, what are they?  Dbfirs 20:33, 1 May 2011 (UTC)
replies: text:  From usage, a triamb(us) appears to be a hexagon with equal sides and threefold rotational symmetry. A regular hexagon is to triambs as a square is to rhombs. —Tamfang (talk) 23:44, 1 May 2011 (UTC)
replies: text: Thanks.  I can picture them now.  (e.g. take two squares and cut each across a diagonal then take three of the four right-angled pieces and fit them together to form a hexagon with alternating right-angles and 150 degree angles.)

text:  I've not seen these names used for convex polyhedra, but seems to be used in the uniform star polyhedral duals like medial triambic icosahedron, (and similar great triambic icosahedron), names created by Norman Johnson I expect! If Tamfang's definition is correct, this term doesn't rightfully belong as usage in regular hexagons - that would be like calling a square a rhombus, true but under-qualified. Tom Ruen (talk) 00:56, 2 May 2011 (UTC)
replies: text: I suppose one could call them semi-regular hexagons?  The adjective triambic possibly deserves a Wiktionary entry since it seems to be used in the works of more than one author.  Is the same true of triamb and triambus?  Dbfirs 06:57, 2 May 2011 (UTC)
replies: text:  Semi-regular isn't the right word. Semiregular polyhedra are vertex transitive. These would be isotoxal figures (edge-transitive), so it would be an isotoxal hexagon. Tom Ruen (talk) 18:52, 2 May 2011 (UTC)
replies: text:  Thanks, I wasn't aware that mathematicians had chosen to use "semi-regular" for only half of it's possible meaning.  It's not a precise description anyway -- your precise terms are much better, but might be slightly too technical for a basic article on a 2-D figure because they are normally applied to polyhedra.  Do you think we should add a section on equilateral hexagons that are not equiangular but have some rotational symmetry?  (and, I suppose, on equiangular hexagons that are not equilateral but have a line of symmetry) -- or are they too trivial to be worth mentioning?  Dbfirs 07:36, 3 May 2011 (UTC)
replies: text: A triambus is a hexagon which is equilateral but not equiangular (a sort of hexagonal rhombus), while a ditrigon is a hexagon with alternating edge lengths and is equiangular (a sort of hexagonal rectangle). These two can be extended to any number of sides: an octambus would be an equilateral but not equiangular hexadecagon, and a dipentagon would be an equiangular decagon with alternating edge lengths. (The di-n-gon can also be extended to fractional n, like the dipentagram or distellagon when n = .) Double sharp (talk) 09:45, 12 August 2012 (UTC)
