triangle problem

For a triangle with vertices A, B and C, determine if a vertex X lies on the plane defined by the three vertices of triangle.

Here I assume that since vertex X lies on plane, find coordinates and perpendicular distance from point, then check if vertex X lies. What is the equation here?


  • My approach is to check to see if the vertex lies in the plane of the triangle. Then project the triangle and vertex into 2D.

    Any suggestions?
