Thanks jeroen, now I have solved the problem and your help has been very useful!

Ok jeroen, now I understand your previous answer: to compute the distance of the point to both lines (x axis and y axis), and I will have the coordinates, but how can I know the negative or plus sign, please?? Sorry, but I have not idea of geometry.

Ok, I have a series of points in a plane, and two perpendicular lines contained in this plane (I know the intersection point, which I want it to be the 0,0,0). I need to determine the quadrant (regarding the reference system composed by the two perpendicular lines) the points belong to. The...

Hi, I still have another problem: I want the two lines (perpendicular and contained in the same plane) to be a new reference system. As above jeroen has said, the changes of coordinates is carried out, and considering the intersection of the two lines as the new origin, this point will be 0, 0...

Thanks, jeroen. Your suggestion works. Now I can know the quadrant points belong to

Hi, I think this problem isn't too complicated, but I am not good at geometry. Can you help me? I want to transform the origin of a cartesian system. I have a plane (Ax +By +Zc +D = 0) and two perpendicular lines, contained in the plane. I have the equations (parametric) of the two...
