the empty set, $\varnothing$, if the lines or planes don't intersect.

a list of coordinate values, if the intersection is a point.

a Line or Plane object, if that is the intersection.

The GetIntersection command obtains the intersection of two point, Line, or Plane objects as understood by the Student[MultivariateCalculus] package.

The Intersects command can be used to test if lines and/or planes intersect.

The empty set, denoted by $\varnothing$, is returned if the lines or planes do not intersect.

If one object is contained in another, then their intersection is the smaller object. In particular, the intersection of any object $A$ with itself is that object $A$.
