I know there is a difference between orthogonal and perpendicular, but don't specifically know what the difference is... Can someone explain?

And can you explain how orthogonal tends to be used when discussing planes?  What do planes have to do with orthogonal?

Thanks. Answers are very appreciated!!

In terms of lines an planes, they're the same thing. They only become different when you start thinking in more abstract terms about what 'orthogonal' means.

In terms of planes, two orthogonal or perpendicular planes are just two planes which meet at an angle of 90 degrees, like the faces of a cube.

Orthogonality is used to describe vectors.  Two vectors are orthogonal if they are perpendicular.

In terms of planes, a vector is orthogonal to it, if it is perpendicular to the surface of the plane.
