Understand the basic concept of equation of a Plane in 3-D Geometry

Any student of 3-D Geometry in Class 12 will benefit from these formulas because it will help you in problem solving.

This lesson helps you to understand the 2 basic forms in determining the equation of a plane in 3-D Geometry

As a mathematics teacher, teaching for over 2 decades, I have seen that this is a formula which is very often misunderstood by students. You need to differentiate between the unit normal to the plane and just a normal vector to the plane.
