Find an equation of a plane that is perpendicular to the plane

A door is perpendicular to the floor. .Swing the door

. . and you have thousands of planes perpendicular to the floor.

Our plane can go through any point, say,

Its normal vector, , must be perpendicular to

Hence, we have: .

. . We can use, for example: .

The equation is: .
