C 11. Show that if, from the foot of a perpendicular to a plane, a line is drawn normal to any line in the plane, the line connecting this point of intersection with any point in the perpendicular is normal to the line in the plane. Hint. Draw AB perpendicular to plane RS, BC perpendicular to DE in the plane, and PC from C to P, in AB. Take CD = CE; draw PD, PE, BD, BE.
