what shape has 10 sides?

easy, it's called decagon!

There are two names for a seven sided shape, heptagon and septagon.  Both answers are equally correct

that is one of the answers, if the length of one side is 5. Use the Phytagorous theorem.

Zeroth dimension = point\nFirst dimension = line\nSecond dimension = square\nThird dimension = cube\nFourth dimension = tesseract\nFifth dimension = decateron\n\nThe rests have names (I've lost the website), but what you are listing is the names of polygons (at least after the tesseract), all two-dimensional objects.\n\nA two dimensional object with:\n3 sides = triangle\n4 sides = square\n5 sides = pentagon\n6 sides = hexagon\n7 sides = heptagon\n8 sides = octagon\n9 sides = nonagon\n10 sides = decagon\n\nSee the below for the construction of the rest of the names:

1/6 coz there r 6 sides on  a die  i dunno

The parallelograms would be formed by combinations of two lines from the first set and two from the second set.  The number of combinations of two from the set of ten is 10*9/2 = 45.   The number from the second set is 9*8/2=36.  The total formed is 45*36 = 1620

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

10cm on a side. I think this is what you want.

polyhedron (pŏl'ēhē'drən) , closed solid bounded by plane faces; each face of a polyhedron is a polygon. A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles. Although regular polygons are possible for any number of sides, there are only five possible regular polyhedrons, having congruent faces, each a regular polygon and meeting at equal angles. The five regular polyhedrons are also known as the Platonic solids, although they were known to the Greeks before the time of Plato. They are the tetrahedron, bounded by four equilateral triangles; the hexahedron, or cube, bounded by six squares; the octahedron, bounded by eight equilateral triangles; the dodecahedron, bounded by twelve regular pentagons; and the icosahedron, bounded by twenty equilateral triangles. The 18th-century Swiss mathematician Leonhard Euler showed that for any simple polyhedron, i.e., a polyhedron containing no holes, the sum of the number of vertices V and the number of faces F is equal to the number of edges E plus 2, or V+F=E+2

could be circle because it doesn't have any sides or angles\n\ncould be rectangle because it is not proportional (side-wise.. and only if the triangle is equilateral)\n\ncould be triangle because if all shapes are placed right-side and divided into four equal parts, like a cross-hair, the triangle is the only one without equal portions.

There are in infinate number of 2d shapes, but here are diagrams of some of them --> http://www.mathleague.com/help/geometry/polygons.htm

a polygon with 5 sides is a pentagon.\n\nthis has two right angles so it would look like the picture of a basic drawing of a house.   see the pic of the house attached.\n\nhttp://www.thestationerystudio.com/index.cfm/fuseaction/catalog.viewProduct/productId/5214
