Platonic Solids-Faces, Edges, Vertices
A soild with all flat surfaces that enclose a single region of space is called a polyhedron. each flatsurfaceor face is a polygon. The line segments where the faces intersect at a point called a vertex.
In geometry, a Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex; thus, all its edges are congruent, as are its vertices and angles.
