Thank-you, this is very interesting. I study descriptive geometry through orthographic projection. You say that line AB is perpendicular to any line in plane pi. Should we clarify this statement by saying that AB is perpendicular to any line in plane pi that passes through point B, the foot of the perpendicular from A ? We cannot say that AB is perpendicular to any line in plane pi that does not pass through point B can we?
