By elementary arguments of linear algebra and vector algebra we give here a proof of Pohlke's fundamental theorem on oblique axonometry. We also present explicit formulae for the reference trihedrons (Pohlke matrices) and the corresponding directions of projection.
Keywords: Pohlke's theorem, oblique axonometry.
