Riemannian geometry Definition

Rie·mann·ian geometry (rē män′ē ən)

noun

a form of non-Euclidean geometry in which there are no parallel lines, since its figures can be conceived as constructed on a curved surface where all straight lines intersect, and in which the sum of the angles of a triangle exceeds 180°

Etymology: after G. F. B. Riemann (1826-66), Ger mathematician
