	Is it possible to have a quiz on the different types of quadrilaterals?

	austin massachusetts:	Oct 31st, 2008 at 12:05 GMT	29 points
	Henagons and Diagons aren't closed figures...

	charlie:	Nov 7th, 2008 at 17:55 GMT	16 points
	what about nonagon? for 9 surely?

	jkd:	Dec 1st, 2008 at 18:51 GMT	16 points
	I know not every quadrilateral is a square, but the title says "shown below". If that quadrilateral is not a square I would be very surprised. (The other polygons all appear regular, too, as in having sides of equal length.)

	jkd:	Dec 1st, 2008 at 18:53 GMT	5 points
	@kania is high: I can only imagine such figures being closed in a non-Euclidean geometry, such as on the surface of a sphere.

	magister:	Dec 2nd, 2008 at 02:13 GMT	4 points
	@jkd: There is no indication that the sides of any of the polygons are congruent.

	Is this the shape of things to come on Sporcle?

	Etheridge2:	Jan 30th, 2009 at 18:37 GMT	13 points
	septagon for heptagon should be allowed and I thought a polygon had to be closed so there are no 1 and 2 sided polygons

	Qrystal:	Feb 6th, 2009 at 15:34 GMT	1 point
	Nice! I didn't think about curved surfaces to allow for 1 and 2 sided pologons!

	Maverick197:	Mar 28th, 2009 at 20:49 GMT	8 points
	Ya... mathematically there are a lot of problems with the definitions you've chosen and the fact that you don't recognize alternates. Basically you're just applying greek prefix's to 'gon' and saying that's all to be said about this but, for example, your quadrilateral could just as correctly be called a tetragon or quadrangle and, as has been pointed out, 1 and 2 dimensional polygon's are very ill-defined

	fussballgott:	Apr 11th, 2009 at 03:27 GMT	8 points
	1 sides and 2 sides arent closed figures, so they should not be on a polygon quiz

	Amanda:	Apr 24th, 2009 at 01:02 GMT	9 points
	in order to be considered a polygon the shape... - must be closed - have 3 or more sides - contain no curved lines - have no intersecting lines therefore, the first two shapes listed are NOT "polygons". also, septagon is mathematically accepted as the name for a 7-sided polygon, as well as heptagon. It should be accepted for the quiz.

	the only way i should have known the 11 sided one was a Susan B. Anthony dollar. but no luck remembering this early in the morning

	the quadrilateral shown is a square.

	Walton:	May 19th, 2009 at 02:21 GMT	3 points
	technically a shape with only 1 edge is not a 'poly'gon by definition....and it's a circle ffs!

	GeoExpert:	Jun 12th, 2009 at 15:33 GMT	0 points
	Henagon and digon! Those should have been bonuses, not real answers! Without them I would have had a perfect score

	GeoExpert:	Jun 12th, 2009 at 15:33 GMT	9 points
	Speak the truth people. Who guessed square for quadrilateral?

	Secret_Asian_Man:	Jun 14th, 2009 at 13:50 GMT	-1 points
	Henagons and digons are closed figures in non-Euclidian geometry. There is no indication to indicate that the angles and sides of that quadrilateral are congruent, so there is no way of knowing whether or not it is a square.

	mango:	Jun 19th, 2009 at 21:22 GMT	0 points
	what the hell is a henagon!

	Rom:	Jul 6th, 2009 at 02:16 GMT	8 points
	I agree with Walton, henagons and digons are not polygons, which is the title of the quiz. Point and line should work for those two.

	Disclaimer:	Aug 6th, 2009 at 23:42 GMT	4 points
	Every definition of "polygon" I've been able to find specifically included "at least 3 sides". Am I wrong that a 1 or 2 sided figure is by definition not a polygon?

	buppyspek:	Aug 17th, 2009 at 18:10 GMT	3 points
	GeoExpert: I did. I also tried "rectangle," "rhombus," and "parallelogram."

	gamer2000:	Aug 19th, 2009 at 00:08 GMT	-1 points
	no mathmetician here, I'd get the same ones wrong if I did over again.... HA

	mb8094:	Sep 19th, 2009 at 09:36 GMT	-1 points
	the quiz accepted nonagon for 9-sided. I think it should have accepted square for 4-sided, since quadrilateral is a class of shapes with 4 sides. I agree with @disclaimer that 1 & 2 sided shapes aren't classed as polygons.

	twenty8penguin:	Oct 22nd, 2009 at 21:06 GMT	5 points
	Sexagon and Septagon are both common use alternatives for Hexagon and Heptagon, respectively.

	nadski:	Nov 13th, 2009 at 21:48 GMT	1 point
	henagons and digons aren't polygons...i spent a really long time writing things like "none" or "not a polygon" trying to make it work...and i tried line segment and circle for one...i was so confused haha :P

	Absentia:	Dec 5th, 2009 at 03:29 GMT	2 points
	Pretty sure a square is "the polygon shown below."

	jdaster64:	Dec 8th, 2009 at 06:21 GMT	4 points
	Quadrangle, Square, and Rectangle should all be alternates for Quadrilateral, and Henagon/Digon should probably be removed or clarified.

	ninjasrockmysox:	Dec 19th, 2009 at 23:29 GMT	1 point
	how about just accepting square for the four sided figure, instead of quadrilateral? ill bet you that most people type in square for that spot, and then get confused as to why it wasnt accepted... i mean, why not just call a triangle a polygon? i guess the reasoning would be that there is no guarantee that the shape is a square, since we dont know the measurements of the sides, but no need to get too technical for a simple quiz like this..

	blazikenkenken:	Dec 21st, 2009 at 01:11 GMT	1 point
	It honestly took me a few tries to get quadrilateral x_x

	atoms12123:	Dec 25th, 2009 at 22:39 GMT	1 point
	Really, 1 and 2 sides can't be polygons cause of the whole thing with polygons are closed figures with at least 3 sides, no curved edges. Also nonagon is nine sided I believe and hepta or septa should be the same. That is defianately a square. So it should except quadrilateral, quadrangle, square, rhombus, rectangle.

Comment below threshold: show it

	mew:	Jan 27th, 2010 at 23:04 GMT	1 point
	Polygons are supposed to be closed figures... so what would a henagon or a digon even look like? And a square can also go by the names of most other quadrilaterals.

	lilkon27:	Jan 31st, 2010 at 15:16 GMT	0 points
	4 sided figures can also be rectangles, so quadrilateral is supposed to be right. i learned that after square didnt work. and btw what the heck is a henagon or a digon? those arent real polygons.

	Simmer_15:	Feb 9th, 2010 at 20:52 GMT	2 points
	thank you geometry class

	joe7136:	Mar 25th, 2010 at 21:42 GMT	1 point
	that 4 sided figure can be a rectangle, rhombus, square, or even a parallelogram...

	i_am_the_best:	Apr 23rd, 2010 at 22:41 GMT	4 points
	i always thought that 7 sides was a septagon...

	sobdennis:	Jul 7th, 2010 at 06:00 GMT	3 points
	I think that if you are going to have one and two sided figures in a quiz about polygons, you should at least accept line and angle. Every math class I ever took told me that a one sided figure was a line and a two sided figure was an angle.

	deadeye:	Sep 19th, 2010 at 23:45 GMT	2 points
	Henagons and digons?? You mean lines and circles?
