A dodecahedron is a convex body.
In mathematics, a convex body in -dimensional Euclidean space is a compact convex set with non-empty interior.
A convex body is called symmetric if it is centrally symmetric with respect to the origin; that is to say, a point lies in if and only if its antipode, also lies in Symmetric convex bodies are in a one-to-one correspondence with the unit balls of norms on
Important examples of convex bodies are the Euclidean ball, the hypercube and the cross-polytope.
