What is another word for non-euclidean?
Pronunciation: [nˈɒnjˌuːkla͡ɪdˈi͡ən] (IPA) 
Non-Euclidean geometry is a branch of mathematics that departs from the traditional rules and principles of Euclidean geometry. This deviation is mainly due to the modification of Euclid's fifth postulate or the parallel postulate. The word non-Euclidean has a unique meaning and usage, but there are synonyms that can be used interchangeably to express similar concepts and ideas. Some of these synonyms include "non-standard geometry," "non-classical geometry," "hyperbolic geometry," and "elliptic geometry." Each of these terms relates to the study of geometry concepts that differ from the traditional Euclidean geometry. Despite their differences from one another, they all fall under the category of non-Euclidean geometry.
