text: The vertices of the Icosahedron can be easily obtained from three mutually orthogonal Golden rectangles, whose sides are in a proportion 1:φ (the actual edge length of all the polyhedra shown in the figures of this article is twice the one shown by the blue arrows that indicate the Golden proportions).
text: Starting with the eight vertices of a cube, the remaining twelve vertices can be obtained from three orthogonal rectangles also related to the Golden Ratio, but in a proportion 1:φ2 instead of 1:φ as in the icosahedron (Figure 3):
