Euclidean geometry  Wikipedia
Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the Elements.Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions from these.

NonEuclidean geometry  Wikipedia
In mathematics, nonEuclidean geometry consists of two geometries based on axioms closely related to those specifying Euclidean geometry.As Euclidean geometry lies at the intersection of metric geometry and affine geometry, nonEuclidean geometry arises when either the metric requirement is relaxed, or the parallel postulate is replaced with an ...

NonEuclidean geometry: NonEuclidean geometry, literally any geometry that is not the same as Euclidean geometry. Although the term is frequently used to refer only to hyperbolic geometry, common usage includes those few geometries (hyperbolic and spherical) that differ from but are very close to Euclidean geometry (see

This is a challenging problemsolving book in Euclidean geometry, assuming nothing of the reader other than a good deal of courage. Topics covered included cyclic quadrilaterals, power of a point, homothety, triangle centers; along the way the reader will meet such classical gems as the ninepoint circle, the Simson line, the symmedian and the ...

Anti deSitter space. When dealing with geometries that take place within the Universe, we deal not with conventional threedimensional euclidean geometry, we have to adapt it to represent a fourdimensional spacetime.

Later in life, Gauss also claimed to have investigated a kind of nonEuclidean geometry using curved space but, unwilling to court controversy, he decided not to pursue or publish any of these avantgarde ideas.
