I need directions for turning 2D shapes into 3D shapes for math class.?

Well, if you think about it, you shouldn't have to copy. To make any shape 3D from 2D, just give it DEPTH. Draw lines slightly up and tilted from each corner, then connect them accordingly. It's super easy once you get the concept.\n\nFor pictures, go to www.mathworld.com and search for cubes, prisms, etc.

just draw a triangle has right angle which dimensions 1,sqrt(3),and hypothenus 2. if you want it, i can send to you

Firstly ..... What format ? Do you have Autocad, Pro-Engineer or what ?\nThere are plenty of sites that do 3D models for free on the web, but cant point you in the right direction without knowing what programme you are using, sorry.\nOf course, if push came to shove I could just do one for you.

if you are asking .. how to sketch an eclipse ... take two verticies (two spots some distance apart left to right on a page) ... and using a compass play with intersecting the radius' of different lengths ... you will find that if you pick the one of equal length as the distance from the vertices ... you will get an intersection of the two radius' from the original vertices ... then playing with the new found radius' ... you will be able to place arcs on the ajoining vertices to creat the other two arcs and blend them together creating an approximate elipse ... a french curve help too

The simplest way is to cut it into five slices, each with an arc of 72 degrees (or 2*pi/5 radians). You could probably also figure out a way to cut it into strips so that each strip has equal area, but that would be significantly more complicated.

You can use a modelling tool such as 3dsMax, Maya, Lightwave and many more. For the first lesson, make a cube and paste the texture to the cube and translate and rotate the cube to see the effect. Save it as video format (Render) and see the result.\n\nTo have more control on the 3d modelling you need to learn DirectX.

Cut out a cardboard circle, draw colors on that or glue the color wheel on it.\nPut a needle through the centre (as the axis) and use 2 forks to hold the needle.\n\nIf you need a lot of spin, tie a rope around the needle and pull

you can create numbers and shapes out of cardboard\ncreate cone/hat out of nice colored paper.\nand of course put a string trough with needle

Build an abacus.  \nArrange 10 beads on a piece of piano wire.  Every fifth bead should be a different collor.\n--oo--oo0-oooo0--\nMake a few more strings and mount them together in parallel or inline with each other.\n------ooooxoooox\nooo----oxoooox--\n--ooooxoo----ooo\n\nA really cool math based model would be a display of geometric shapes.\n\nYou could go to the matherworld site and print out some patterns for the platonic solids.  Then cut them out and fold them together.  The collection can be displayed in a couple of ways.  The easiest would be to mount them on straws poking out from a block of styrofoam.  The most dramatic would be to arrange them to hang in a mobile.  If you want instructions on making a mobile, send an email to samphelps at yahoo.\n\nPlatonic solids are the 3 dimensional shapes where all the sides are the same.  The most familiar is a cube where each side is a square.  Another is the tetrahedron where each side is a triangle.

Try the moebius spiral. It's pretty interesting because it's non orientable. \n\nIt's 3d (2 parameters s and t) and described by the parametrized vector components:\n\n[3*cos(s)+t*sin(s/2),\n3*sin(s),\nt*cos(s/2)]\n\n(every component of the vector in a new line)\n\nThe parameter ranges are:\n\ns=-2*Pi...2*Pi,t=-1..1\n\nMAPLE INSTRUCTIONS TO PLOT IT:\n\nwith(plots);\nplot3d([3*cos(s)+t*sin(s/2),3*sin(s),t*cos(s/2)],s=-2*Pi...2*Pi,t=-1..1);\n\nSorry, that instruction is big and not displayed well, but I guess since you know the parametrized vector you can find it.\n\nWHAT DO YOU WANT IT FOR? WANT TO PUBLISH ANYTHING?
