All Platonic solids are convex regular polyhedra symmetrical about their centers.
Platonic solids are 3-dimensional shapes that look identical from every vertex and are composed of only one type of regular polygon (1).
The cosmos is both an abstract set of laws--the four elements, the perfect circular orbits, Platonic solids etc--and a particular history, a one-off event, a singular evolutionary chain.
The primary thesis in the Mysterium cosmographicum is that God created the (Copernican) universe to express the five platonic solids (the cube, tetrahedron, octahedron, icosahedron, and dodecahedron).
Students can also mark edges, vertices, and faces to highlight these aspects on Platonic solids.
Platonic solids, Archimedian solids, other geometric solids, and the mathematical relationships related to these solids were the objects of study.
