Samuel Johnson's Dictionary

  1. GEOMETRYnoun

    Originally signifies the art of measuring the earth, or any distances or dimensions on or within it: but it is now used for the science of quantity, extension, or magnitude abstractedly considered, without any regard to matter.

    Etymology: γεωμετρία; geometrie, French.

    Geometry very probably had its first rise in Egypt, where the Nile annually overflowing the country, and covering it with mud, obliged men to distinguish their lands one from another, by the consideration of their figure; and after which, ’tis probable, to be able also to measure the quantity of it, and to know how to plot it, and lay it out again in its just dimensions, figure and proportion: after which, it is likely, a farther contemplation of those draughts and figures helped them to discover many excellent and wonderful properties belonging to them; which speculations were continually improving, and are still to this day. Geometry is usually divided into speculative and practical; the former of which contemplates and treats of the properties of continued quantity abstractedly; and the latter applies these speculations and theorems to use and practice, and to the benefit and advantage of mankind. John Harris.

    In the muscles alone there seems to be more geometry than in all the artificial engines in the world. John Ray, on the Creation.

    Him also for my censor I disdain,
    Who thinks all science, as all virtue, vain;
    Who counts geometry and numbers toys,
    And with his foot the sacred dust destroys. John Dryden, Pers. Sat.

Webster Dictionary

  1. Geometrynoun

    that branch of mathematics which investigates the relations, properties, and measurement of solids, surfaces, lines, and angles; the science which treats of the properties and relations of magnitudes; the science of the relations of space

  2. Geometrynoun

    a treatise on this science

  3. Etymology: [F. gomtrie, L. geometria, fr. Gr. , fr. to measure land; ge`a, gh^, the earth + to measure. So called because one of its earliest and most important applications was to the measurement of the earth's surface. See Geometer.]


  1. Geometry

    Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths, areas, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow. Archimedes developed ingenious techniques for calculating areas and volumes, in many ways anticipating modern integral calculus. The field of astronomy, especially mapping the positions of the stars and planets on the celestial sphere and describing the relationship between movements of celestial bodies, served as an important source of geometric problems during the next one and a half millennia. Both geometry and astronomy were considered in the classical world to be part of the Quadrivium, a subset of the seven liberal arts considered essential for a free citizen to master.

Chambers 20th Century Dictionary

  1. Geometry

    je-om′e-tri, n. that branch of mathematics which treats of magnitude and its relations: a text-book of geometry.—ns. Geom′eter, Geometri′cian, one skilled in geometry.—adjs. Geomet′ric, -al.—adv. Geomet′rically.—v.i. Geom′etrise, to study geometry.—n. Geom′etrist. [Fr. géométrie—L., Gr. geometria, the earth, metron, a measure.]

Military Dictionary and Gazetteer

  1. geometry

    That branch of mathematics which investigates the relations, properties and measurements of solids, surfaces, lines, and angles; the science which treats of the properties and relations of magnitudes. Its usefulness extends to almost every art and science. It is by the assistance of geometry that engineers conduct all their works, take the situation and plans of towers, the distances of places, and the measure of such things as are only accessible to the sight. It is not only an introduction to fortification, but highly necessary to mechanics. On geometry, likewise, depends the theory of gunnery, mining, mechanics, hydraulics, pneumatics, etc.

Examples of geometry in a Sentence

  1. Thomas Jefferson:

    Our civil rights have no dependence on our religious opinions, any more than our opinions in physics or geometry.

  2. Yonatan Winetraub:

    [Philae] was a completely different problem – the moon’s gravity is significantly stronger … the Moon’s geometry is very well understood – we have got a good idea of where we will land, we’re doing our best – it is rocket science!

  3. Andrew Chamberlain:

    The existence of these measuring devices implies an advanced knowledge in prehistoric Britain of geometry and of the mathematical properties of circles.

  4. Kedar Joshi:

    In reality the universe has no geometry.

  5. Laura Bachrach:

    We’re really worried about this because there’s sort of this critical time between being born and reaching the early 20s when you’re setting up the scaffolding of life (in terms of the geometry and density of the bone), you sort of max out in your early 20s and there is real concern that the lifestyle of young people nowadays versus 40 or 50 years ago is setting people up to be more at risk as adults for not having a very robust bone bank as they age.
