I'm sure this is a really simple question but I would appreciate if somebody could explain it or point me in the right direction.

If I have a point in 3D space that is of unit length from an origin, can I represent it as a matrix of angles or use angles in some way to represent the original set of coordinates? I'm wanting to show it's position in relation to a plane spanned by two other points (again of unit length)

Also, if it was not unit length how would I incorporate that info?
