This chapter presents Euclid's fifth postulate, which states that if a straight line falling on two straight lines makes the interior angles on the same side together less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which the angles are ...

This century saw the development of the two forms of non-Euclideanw非欧几里得 geometry, where the parallel postulate假设 of Euclidean geometry no longer holds. The Russian mathematician Nikolai Ivanovich Lobachevsky and his rival竞争对手, the Hungarian mathematician János Bolyai, independently defined and...
It is the embryonic form ofGauss–Bonnet formula. Parallel is one of the most fundamental concepts in mathematics and influenced modern physics. Trisecting angle and squaring circle are the straightedge and compass construction problems put forward by the Greeks, one associated withGalois groupand o...

Ancient Greek mathematicians started to be suspicious about Euclid's fifth postulate --- the parallel postulate...
be suspicious about Euclid's fifth postulate --- the parallel postulate, and tried to prove it by the other four axioms. This idea influenced the development of mathematics. The parallel postulate is equivalent to the triangle postulate, which ...

Beginning in the 19th century, various mathematicians substitutedalternativesto Euclid’sparallel postulate, which, in its modern form, reads, “given alineand a point not on the line, it is possible to draw exactly one line through the given point parallel to the line.” They hoped to show ...
The parallel postulate is the basic one in this geometry, which states that there can be only one line parallel to a given line through a point not on it. InEuclidean geometry: Lines remain straight, and shapes behave as expected on a flat plane. ...
