Pohlke's Theorem

The principal theorem of Axonometry. It states that three segments of arbitrary length , , and which are drawn in a Plane from a point under arbitrary Angles form a parallel projection ofthree equal segments , , and from the Origin of three Perpendicular coordinate axes. However,only one of the segments or one of the Angles may vanish.
