# On a Plane

Whenever I move, I change planes. How can this be since I never fly?

We can only be perpendicular to one plane at a time, so whenever we move it is always a movement between different planes, in a geometric sense. Thus whenever we move we change planes.Hide Hint Show Hint Hide Answer Show Answer
