    Coplanar 3D points Please help

    Hello,

    I'm given a set of four 3D points to show whether they are coplanar, so I use the scalar triple product. I just need to know in case I have more than four points will this solution work or need to do something else? If yes or no why?

    Thank you

    If you've more than 4 points determine the plane that passes thorugh any three of them and then check whether the other ones are contained in that planes.

    Thank you tonio, so this method works with as many points as we want, but what happens if we work with dimensions higher than three?!

    Exactly the same: a plane is a plane is any dimension > 1.
