From Wikipedia, the free encyclopedia
A normal plane is any plane containing the normal vector of a surface at a particular point.

The normal plane also refers to the plane that is perpendicular to the tangent vector of a space curve; (this plane also contains the normal vector) see Frenet–Serret formulas.
