Rotation Using three coordinates, there is an easy trick to rotate a point by 60 degrees around the origin: rotate the coordinates left, and change all the signs: $$[x, y, z] \rightarrow [-y, -z, -x]$$ (From here its easy to remove the \(z\)-coordinate, as usual, to find: $$[x, y] \rightarrow [-y, x + y]$$ By applying the trick above repeatedly, we can find similar expressions for points rotated by 120, 180, 240, and 300 degrees
