Rhombic Dodecahedron Geometry Diagram - Edge Labels and Structure #226965 (License: Personal Use)

This black-and-white line diagram depicts a rhombic dodecahedron, a convex polyhedron with 12 rhombic faces, 24 edges, and 14 vertices. Edges are categorized and labeled as m (equatorial), r (radial from top/bottom vertices), and z (connecting middle layers), revealing its symmetry and spatial relationships. Dashed lines indicate hidden edges, emphasizing the 3D structure in 2D projection.

Used in mathematics education, crystallography (e.g., describing cubic close packing), and geometry textbooks to illustrate space-filling polyhedra and symmetry. Matches user intent for visual learning, academic reference, or STEM resource development.
