Dec 18, 2018 at 14:34 comment added Michael E2 Also proj = NullSpace[N@listofnormals] will give you the projection matrix. Note it's important that the input be (approximate) Real numbers. If they're integers or other exact numeric quantities, then the rows of proj won't be orthonormal in general..

Dec 18, 2018 at 4:44 comment added halirutan Your polygon lies in a 2d plane within the 3d space. What you probably want is to project your points along the normal of the plane that is spanned by the polygon. As David pointed out, this does not work in general but in your case this should do the trick.

Dec 18, 2018 at 2:58 comment added Felix Garner @David G. Stork, when I stated "n-dimensional figures with 2-dimensional geometries", I essentially meant 2-dimensional polytopes embedded in n-dimensional spaces, with n some integer greater than 2. I have also clarified my original question to avoid confusion.
Dec 18, 2018 at 2:54 comment added David G. Stork It is mathematically impossible to "preserve angles and distances" when projecting a three-dimensional figure onto a two-dimensional plane. Just think of the 8 vertexes of a cube, for instance.
