Polyhedron geometry definition
WebThe properties of this shape are: All the faces of a convex polyhedron are regular and congruent. Convex polyhedrons are 3D shapes with polygonal faces that are similar in form, height, angles, and edges. In a convex polyhedron, all the interior angles are less than 180º. The diagonals of the shape lie within the interior surface. WebThe polyhedron is then the Minkowski sum.
