Projection of a PointTo look into Projection Mathematically – we consider projection of Point P in 2D plane M. Consider a point P in space, and a plane M. Imagine a line from P intersecting the plane M at a point O. We say that OP is perpendicular to the plane if for any line OX on the plane, ∠POX = 90°. In this case, we say that point O is the projection of point P on the plane. Now, let’s look into Projection of a Line
