circumscription
In plane geometry, the construction of a circle such that all vertices of a particular polygon lie on its circumference, the polygon then being said to be inscribed within the circle. All regular polygons and all triangles may be circumscribed. In three dimensions circumscription implies the construction of a sphere such that on its surface lie all the vertices of a polyhedron.
