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. WebThus a postulate is a hypothesis advanced as an essential presupposition to a train of reasoning. Postulates themselves cannot be proven, but since they are usually self-evident, their acceptance is not a problem. Here is a good example of a postulate (given by Euclid in his studies about geometry). Two points determine (make) a line.
