→How to find the equation of a plane from three points: clean up & uniformity
<br>AB cross BC = <D, E, F>
<br>AB cross BC = <D, E, F>
<br>(D, E, and F stand for the numbers found when the cross product is calculated.)
<br>(D, E, and F stand for the numbers found when the cross product is calculated.)
The equation of the plane is then D(x - x<sub>A</sub>) + E(y - y<sub>A</sub>) + F(z - z<sub>A</sub>) = 0
