Distance	Point	Line	Plane	Sphere	Cylinder
Point	The distance vector is equal to the difference of the local vectors of the two points	The distance vector is perpendicular to the line.	The distance vector is perpendicular to the plane.	The distance is the distance of the sphere center from the point.	The distance is the distance of the cylinder axis from the point. The distance vector is perpendicular to the cylinder axis.
Line	The distance vector is perpendicular to the line.	The distance vector is perpendicular to both lines in space.	The distance vector is perpendicular to both the line and the plane.	The distance is the distance of the sphere center from the line. The distance vector is perpendicular to the line.	The distance is the distance of the cylinder axis from the line. The distance vector is perpendicular to both the line and the cylinder axis.
Plane	The distance vector is perpendicular to the plane.	The distance vector is perpendicular to both the line and the plane.	The distance vector is perpendicular to both planes. For planes to have a distance > 0, they must be parallel.	The distance is the distance of the sphere center from the plane. The distance vector is perpendicular to the plane.	The distance is the distance of the cylinder axis from the plane. The distance vector is perpendicular to both the plane and the cylinder axis.
