Euclidean geometry - Wikipedia
Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, which he described in his textbook on geometry, Elements. Euclid's approach consists in assuming a small set of intuitively appealing axioms (postulates) and deducing many other propositions from these.

A few simple observations lead to a far superior method: Euclid’s algorithm, or the Euclidean algorithm. First, if d divides a and d divides b, then d divides their difference, a - b, where a is the larger of the two. But this means we’ve shrunk the original problem: now we just need to find gcd (a, a − b). We repeat until we reach a trivial case.
Loosely speaking, a non-Euclidean geometry is a model for which a parallel through an off-line point either doesn’t exist or is non-unique. It wasn’t until the 17–1800s and the development of hyperbolic geometry (Chapter 4) that a model was found in which Euclid’s first four postulates hold but for which the parallel postulate is false.6

2022年5月21日 · Euclidean geometry, sometimes called parabolic geometry, is a geometry that follows a set of propositions that are based on Euclid's five postulates. There are two types of Euclidean geometry: plane geometry, which is two-dimensional Euclidean geometry, and solid geometry, which is three-dimensional Euclidean geometry.

2014年10月25日 · The space of Euclidean geometry is usually described as a set of objects of three kinds, called "points" , "lines" and "planes" ; the relations between them are incidence, order ( "lying between" ), congruence (or the concept of a motion), and continuity.
Euclidean Geometry: Principles, Theorems - StudySmarter
Euclidean geometry, a mathematical system attributed to the Alexandrian Greek mathematician Euclid, is the study of plane and solid figures on the basis of axioms and theorems. This foundational framework, established in Euclid's seminal work "Elements", lays the groundwork for understanding shapes, sizes, and the properties of space, playing a ...
