Suppose an icosahedron is centered at the origin and three of its twelve vertices are at
(0, 0, 1), (0, 0,−1), and (a, 0, b). What are the values of a and b?
It is hard for me to picture this, if the center is at (0,0,0), I think you can rotate the icosahedron such that one vertex is at the very top and one is at the very bottom, like a north and south poles, but are these points (0,0,1) and (0,0,-1)? If so, how do you find a and b from that.
Any help is appreciated.
