WebThe simplest way to create the dual polyhedron for a Platonic solid is by finding the midpoints of each of the faces, and then connecting these midpoints so that they become the vertices of the new dual polyhedon. Take another look at the picture with the octahedron and the cube. You can see exactly how this method works with Platonic solids. WebApr 13, 2024 · Regular polyhedra generalize the notion of regular polygons to three dimensions.
