Archimedean Solid

... 13 convex polyhedra use regular polygons as faces, possibly using for than one shape.

Convex Polyhedron

... a solid made of flat faces, where a line can cut the polyhedron in at most 2 places

Concave Polyhedron

... a solid made of flat faces, where a line can cut the polyhedron in more than 2 places

Snub

... faces are shrunk (maintaining shape but not orientation) and new polygons added to edges

Platonic Solids

... five regular polyhedron (all edges are equal, all faces are the same regular polygons)

Face

... flat surface of a polyhedron

Truncate

... remove a vertex to create a new face

Edge

... sharp line formed where two surfaces (faces) meet

Vertex

... the point where 3 or more edges meet
