  • n. That branch of mathematics which deduces the properties of figures in space from their defining conditions, by means of assumed properties of space. Abbreviated geometry
  • n. A text-book of geometry.
  • n. Modern projective geometry, commonly written in German Geometrie der Lage, to distinguish it from .

  • n. The art of geometrical drawing.
  • n. Geometry of three dimensions.
  • n. The oldest classification of geometry is , that in which it is divided according to the method of logical procedure, namely into synthetic and analytic, the method of geometrical analysis having been invented or taught by Plato. In modern times this classification intertwines with another, namely , that which is based on the mental instrument or equipment used, giving: pure or synthetic geometry; rational; descriptive; projective; algebraic, algorithmic, analytical, Cartesian, or coördinate; differential, infinitesimal, natural, or intrinsic; enumerative or denumerative. Some of these are subdivided on the same principle, as: (α) geometry of the ruler or straight-edge; (β) of the ruler and sect-carrier; (γ) of the ruler and unitsect-carrier; (δ) of the compasses; of the ruler and compasses; (ζ) of linkages. Further divisions are: By dimensionality: geometry on the straight or on the line; two-dimensional geometry; (α) plane geometry; (β) spherics; (γ) pseudo-spherics; tri-dimensional geometry: (α) geometry of planes; (β) solid geometry; (γ) spherics; four-dimensional geometry: (α) geometry of straight?; (β) of hyperspace; n-dimeimonal geometry. By elements: point geometry; straight or line; plane; point, straight, and plane; straightest or geodesic; geometry of the sphere; of other elements, By subject-matter: pure descriptive, pure projective, or pure positional geometry, or geometry of position; topologic geometry; metric geometry; geometry of curves; of surfaces; of solids; of hyper-solids; of numbers; of motion or kinematic. By assumptions made, omitted, or denied: Euclidean geometry; non-Euclidean; metageometry, or pan-geometry; finite geometry; semi-Euclidean; non-Legendrian; Archimedean; non-Archimedean; non-Arguesian; non-Pascalian. By the kind of space or universe of the geometry: Euclidean or parabolic geometry; Bolyaian, Lobachevskian, Bolyai-Lobachevskian, absolute, or hyperbolic; Riemannian, spherical, or double elliptic; Killing's, single elliptic, or simple elliptic; Clifford's or Clifford-Kleinian. By the complexity or difficulty of the part treated: elementary geometry; higher, By the period of its development: ancient or the antique geometry; modern; recent, of the triangle, or the Lemoine-Brocard.

Etymologies

Middle English geometrie, from Old French, from Latin geōmetria, from Greek geōmetriā, from geōmetrein, to measure land : geō-, geo- + metron, measure; see mē-2 in Indo-European roots.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From Ancient Greek γεωμετρία (geometría, "geometry, land-survey"), from γεωμετρέω (geometréo, "to practice or to profess geometry, to measure, to survey land"), back-formation from γεωμέτρης (geométrēs, "land measurer"), from γῆ (gē, "earth, land, country") + μετρέω (metréō, "to measure, to count") or -μετρία (-metria, "measurement"), from μέτρον (metron, "a measure").

  • Thales kept the Egyptian name “earth measurement” for his mathematics, but being Greek, used the Greek word geometry.

    Euclid’s Window

  • The best known of these men was Euclid, who perfected the mathematics which we call geometry, and Ptolemy, whose ideas about geography and the shape and size of the globe Columbus carefully studied before he set out on his great voyage.

  • Gautier based his refutation of Newton in geometry, as Castel had; a style of argument typical of Jesuit science in the eighteenth century and especially in France. 17 The techniques and terminology common to mathematical proofs are the basis of Gautier's explanation, although, as Étienne Montucla complained in the Journal œconomique, his understanding of geometry is even less exact than his understanding of Newtonian optics. 18 The foundations are similar, but he draws, as part of his proofs, more analogies to interpretations or beliefs common among painters.

  • Atoms come together to form compounds; the geometry is determined by the orientations of the chemical bonds, which are mergers of electron orbitals.
