Planes between PlanesDate: 04/02/2001 at 07:00:54 From: Nikila Subject: Planes How can I find if a plane lies between two other planes? Thanks in advance.

If the planes aren't all parallel, your question is not meaningful: two nonparallel planes intersect, so parts of each plane will lie on either side of the other. Thus I must assume that the three planes are parallel. Write the equations of all three planes in the form A*x + B*y + C*z = D(i), i = 1, 2, 3. You can do this using the same values of A, B, and C for all three. Then the plane with the middle of the three values D(i) will lie between the other two. - Doctor Rob, The Math Forum http://mathforum.org/dr.math/ |
