This is a dodecahedron, a three-dimensional space

We are learning about a Platonic solid which is a polyhedron. It is constructed by congruent (identical in shape and size), regular (all angles equal and all sides equal), polygonal faces with the same number of faces meeting at each vertex. 


We are learning to create a three-dimensional space.This is a dodecahedron. A dodecahedron is composed of:12 regular pentagonal faces, 3 faces meeting at each vertex.  It has 12 faces, 20 vertices, and 30 edges.
