      1 # Plane to Plane Distance

      5 See [DistanceToPlane](DistanceToPlane.md) for distance from plane to point.

      7 This only is useful for planes that are paralell otherwise they will intersect.

      9 Steps:
     10 
     11 1. Find equation of both planes 
     12 2. Find representative point
     13 3. Take [DistanceToPlane](DistanceToPlane.md) from the rep point to the other plane.
     14 
     15 This is true because all points will be the same distance from the other plane given that they are paralell. Otherwise, it would be imperative that they intercect and thus have a min distance of 0.
