3 Regular Ways of Arranging Lines in Space 1The regular polyhedra are like seeds from which growths may appear. They are the connecting joints for the zonohedra. The joints are all parallel to each other. The lines of the zonohedra are perpendicular to the faces of the joints. 3.1 Three Zones 2Figure 3.28: Cube 3.2 Four Zones 3Figure 3.29: Tetrahedron 4Figure 3.30: Octahedron 5Figure 3.31: Rhombic Dodecahedron 3.3 Six Zones 6Figure 3.32: Dodecahedron 7Figure 3.33: Rhombic Triacontahedron 3.4 Ten Zones 8Figure 3.34: Icosahedron 9Figure 3.35: Rhombic Enneacontahedron
