Point 2: (x2,y2,z2)


Point 3: (x3,y3,z3)


  

How does the Equation of a Plane Calculator work?

Given three 3-dimensional points, this calculates the equation of a plane that contains those points.
This calculator has 3 inputs.

What 1 formula is used for the Equation of a Plane Calculator?

  1. Ax + By + Cz + D = 0
    |A| = y1(z2 - z3) + y2(z3 - z1) + y3(z1 - z2)
    |B| = z1(x2 - x3) + z2(x3 - x1) + z3(x1 - x2)
    |C| = x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)
    |D| = x1(y2z3 - y3z2) + x2(y3z1 - y1z3) + x3(y1z2 - y2z1)
