Mathematical model of the physical space

Euclidean geometry is a mathematical system described in Euclid's textbook on geometry; Elements.
Euclid's system assumes a small set of intuitively appealing axioms and deduces many other propositions from these.
Euclidean geometry is an example of synthetic geometry that proceeds logically from axioms describing basic properties of geometric objects.
Euclid gives five postulates for plane geometry, stated in terms of constructions.
Many alternative axioms can be formulated which are logically equivalent to the parallel postulate.
Euclidean geometry is constructive, and its assertions are of a constructive nature: that is, we are not only told that certain things exist but are also given methods for creating them with no more than a compass and an unmarked straightedge.
Euclid often used proof by contradiction and allowed the method of superposition.
Euclidean geometry has two fundamental types of measurements: angle and distance.
The angle scale is absolute, and Euclid uses the right angle as his basic unit.
The distance scale is relative.
Euclid refers to a pair of lines, or a pair of planar or solid figures, as "equal" if their lengths, areas, or volumes are equal respectively, and similarly for angles.
Euclidean geometry has many applications in fields such as architecture, engineering, and physics.Applications and Developments of Euclidean Geometry
Euclidean geometry has been fundamental to mathematics for centuries.
Surveying has been a common and practical use of geometry throughout history.
Euclidean solid geometry helps determine efficient packing arrangements, with applications in error detection and correction.
Geometric optics uses Euclidean geometry to analyze the focusing of light by lenses and mirrors.
Geometry is used extensively in architecture.
Euclidean geometry can be used to design origami.
CAD/CAM design is based on Euclidean geometry, with shapes bounded by planes, cylinders, cones, tori, and other similar shapes.
Archimedes and Apollonius were ancient mathematicians who made significant contributions to geometry.
René Descartes developed analytic geometry, an alternative method for formalizing geometry which focused on turning geometry into algebra.
Non-Euclidean geometry, where the parallel postulate is not valid, was introduced in the 19th century by János Bolyai and Nikolai Ivanovich Lobachevsky.
Albert Einstein's theory of special relativity involves a four-dimensional space-time, the Minkowski space, which is non-Euclidean.
Modern reformulations of Euclidean geometry aim for a cleaner separation of issues such as whether or not space is infinite and what its topology is.Euclidean Geometry: Logic, Rigor, and Axiomatic Formulations
Euclid's proofs often used proof by contradiction
Traditional presentation of Euclidean geometry assumes classical logic
Modern standards of rigor aimed to place Euclidean geometry on solid axiomatic basis
Alessandro Padoa emphasized the role of primitive notions in mathematics
Mathematics is context-independent knowledge within a hierarchical framework
Bertrand Russell also emphasized the hierarchical nature of mathematics
Foundational approaches to mathematics range between foundationalism and formalism
Euclidean geometry has been formulated axiomatically
Euclidean geometry is a subset of projective geometry
Euclidean geometry can be extended using non-Euclidean geometries
Classical theorems in Euclidean geometry include the Pythagorean theorem and the parallel postulate
Euclidean geometry has influenced other fields such as physics and computer science
