Planes and Planes

There are two different ways that two planes can interact.

I. Intersecting Planes

Intersecting planes are two planes that meet.
There are two important factors with two intersecting planes:

A) Two planes will intersect in a single line. This line is a line in each plane.

B) There's no way to construct two planes and have them intersect in more than one line.

II. Parallel Planes
Parallel planes are planes that never meet. Parallel planes always go off in the same direction.

One more point

Given any three intersecting planes, they will intersect in a single point.
