FundamentalsĮuclid realized that a rigorous development of geometry must start with the foundations. See analytic geometry and algebraic geometry.

The modern version of Euclidean geometry is the theory of Euclidean (coordinate) spaces of multiple dimensions, where distance is measured by a suitable generalization of the Pythagorean theorem. In its rigorous deductive organization, the Elements remained the very model of scientific exposition until the end of the 19th century, when the German mathematician David Hilbert wrote his famous Foundations of Geometry (1899). In Euclid’s great work, the Elements, the only tools employed for geometrical constructions were the ruler and the compass-a restriction retained in elementary Euclidean geometry to this day. Rather than the memorization of simple algorithms to solve equations by rote, it demands true insight into the subject, clever ideas for applying theorems in special situations, an ability to generalize from known facts, and an insistence on the importance of proof. It is the most typical expression of general mathematical thinking. Indeed, until the second half of the 19th century, when non-Euclidean geometries attracted the attention of mathematicians, geometry meant Euclidean geometry. In its rough outline, Euclidean geometry is the plane and solid geometry commonly taught in secondary schools.
