Web5 de jun. de 2024 · By the above each of the three projections, restricted to this plane, must be injective, so the plane must be given by an equation a x + b y + c z = 0 with a b c ≠ 0. Then it is geometrically clear that any such plane and any three pairwise nonparallel vectors in it will suffice as column vectors.
