Connection between the golden ratio and the pyramid of the

Louvre.The pentagram is the base of a remarkable pyramid whose lateral sides are golden triangles. If the radius of the base is 1, then its height is φ.If we assemble twelve of these pyramids on the faces of the regular dodecahedron, we get the small stellated dodecahedron. The pyramid of the Louvre is a golden pyramid.
