WebIt sure seems like it. It was probably “controversial” because it seemed much less basic than the first four postulates. If you take alternate postulates such as “there are no parallel lines”, you get interesting geometries, as you’ve been viewing. That can be used for the geometry of a sphere.

Webone based on the first four postulates of Euclid, Euclidean geometry, in which, in addition to the first four, the fifth postulate is added and the hyperbolic geometry already mentioned. The distinct feature of the fifth postulate from the others was stressed long before the appearance of non-Euclidean geometry. WebIn geometry the parallel postulate is one of the axioms of Euclidean geometry. Sometimes it is also called Euclid 's fifth postulate, because it is the fifth postulate in Euclid's Elements .

WebHowever, this too had a fault. In fact, the original postulate that he based the proof on was logically equivalent to Euclid's fifth postulate. (Heath, page 210). Therefore, he had assumed what he was trying to prove, which makes his proof invalid. WebAnswer (1 of 3): You seem to be asking about monotheism.

Through a given point, not on a given line, exactly one line can be drawn parallel to the given line. Playfair’s Axiom is equivalent to the Fifth Postulate in the sense that it can be deduced from Euclid’s five postulates and common notions, while, conversely, the Fifth Postulate can deduced dan white cause of death
