What is a 20 sided shape called??????
962470
a 20 faced polyhedron is called an \nicosahedron-the faces are equilateral\ntriangles\na 20 sided polygon is called an\nicosagon\n\ni hope that this helps

It is not exactly round, just looks that way.\n\nSee webpage below for the correct shape.

Hi I assume you mean an unsymmetrical item. I also assume you want a best fit. I have done similar things on a computer but not by hand. The computer finds three point most distant from the centroid and uses these points as pivots for three orthogonal planes. Not sure of the rest.

if you dont have one already, make a nice big copy of the entire circle with everything labeled.  repetition and review is really just the best way to remember anything.  when i try to think of the unit circle values for 30-60-90 triangles, i just think of it in terms of the long side and the short side.  the short side is always 1/2 and the long side is always (sq. root of 3)/2.  if i need to remember the values for, say, a 120 degree angle, i always draw a quick little sketch- just enough to show which are the short and long sides.  the horizonal is short, so the cosine is 1/2.  the vertical is long, so the sine is (root 3)/2.  this method works for all angles that are multiples of 30 degrees.  45, 135, 225, and 315 degrees are easy because you only have to remember one value for all the sine and cosines: (root 2)/2\n\njust dont forget to look at your sketch to see which of the values is negative! (and if the picture method doesnt work for you, theres a trick to knowing those too . . .\n\nhere are the quadrant numbers: (imagine the axis in between)\n\n2 1\n3 4\n\nuse this acronym to remember what trig functions are positive in each quadrant:\n\nALL---------> ALL of them are positive\nStudents----> Sine is positive\nTake--------> Tangent is positive\nCalculus----> Cosine is positive

hyperbolic\n\nare u not doing your own homework?\n\n\n\n\ntriangle drawn on a sphere always have total angles of more than 180 and they approach 180 as the triangle gets smaller. This type of geometry is called Elliptic Geometry.\n\nAnother type of geometry where all angles add up to less than 180, with 180 being the limiting case, is called hyperbolic geometry.\n\nThe geometry we r familiar with, geomatry of the flat is called Euclidean geometry.

Yes. A polygon is is a closed shape with multiple sides.  Check out all of the other types of polygons here: http://en.wikipedia.org/wiki/Polygon\n\nA rhombus is a polygon with equal sides and angles.  It looks like a slanted square. If you rotate it on end, it is a diamond shape.

Bob, I used to enjoy your show before you started doing all those really expensive houses.  Then, of course, you left.\n\nOh, well.\n\nDon't you know, Bob, that isosceles triangles don't have "right sides?"  An isosceles triangle has two "legs" of equal length.  If it is a right isosceles triangle, the side opposite the right angle is called the hypotenuse.\n\nSay hi to Norm for me!

There are no 3d circles because by definition circle is a 2d figure. The figure obtained by the revolution of a circle around its diameter is called a sphere which is 3-dimensional.\n\nOn the lighter side, if you want to call a 3d circle something, you can call it a "Non-Existant Circle"   :-)

This shape is called the "omega shape", at least as the lower limb of the sun disappears beneath the apparent horizon (the sun has already set quite a bit farther beneath the horizon and one is only seeing so much of the sun because of refraction effects). It is called an omega because it is not strictly an oval or ellipse at that point, and actually has a pair of "feet" at the bottom like an omega. \n\n The actual shape will vary, depending on refraction effects, and those depend on the temperature profile of the atmospheric layers. The shape is typically computed in a simulation by ray-tracing, although one might be able to do some sort of approximation by an ellipse. See the attached link for more details.

shape is anything that has a closed where the open and end meet if it is a closed ending then it is a shape it may not have a name like square or triangle but it is indeed a shape

Ahhhhhhh... isn't it great to be 30 going on 10.  Life it too short to be grown up.  Greatest shaped object huh.... okay well lets see.... you have limited my choices here, that is not fair btw. :p ~ How about a circle.  You can not invert it mathematically.  It has no beginning nor ending.  You can do so many wonderful things with it, such as foot ball, balloons, rings and what not.  It is perfect, yet can not be computed to the last digit (PI) and last but not least, because I say so.  LOL  :)

If you have microsoft word...on the DRAWING toolbar there is an opiton to draw an oval. Hope this helps.

A two dimensional figure is called a dodecagon and a 3D figure with 12 sides is called a dodecahedron.

i think it might be called a triangular prism\ni am srry that was tough i was trying to get it rite so i could get the ten points for best answer. I AM SORRY!

uuuuuhhhhhh, no. a polygon is a MULTI-SIDED figure. hence the POLY prefix, meaning many.
