I have a pentagon for which 3 vertices were chosen to compute the equation of the plane. How to I find the normal passing through its center?
$$P_1 = [ 3.096, \ 0.492, \ 3.287]$$
$$P_2 = [ 3.118, \ 0.227, \ 4.669]$$
$$P_3 = [ 2.214, \ 1.476, \ 2.801]$$
Equation of Plane: $$ 2.809x + 0.732y - 3.586z = 4.614 $$
Given this equation how do I find the normal passing through the center of the pentagon?
