Parallel and Perpendicular Planes
Main Concept
The equation of a plane in can be given as
where A, B, C, D are parameters.
The normal vector to the plane with the above equation is the vector .
Two planes and are perpendicular when their respective normals and are perpendicular:
Two planes and are parallel when their respective normals and are parallel:
Change the coefficients of the Cartesian equation of the planes to see how they change. Select the check box to see the normal vectors.
