Angle Between Planes

Problem

Compute the acute angle between two planes in degrees from their normals n1 and n2:

theta = degrees(acos(|n1 . n2| / (||n1||_2 * ||n2||_2)))

Return None if either normal is the zero vector.

Hint

The angle between planes is the angle between their normals, taken as acute.
