  Geometry \Ge*om"e*try\, n.; pl. Geometries[F. g['e]om['e]trie,
     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. 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.
        [1913 Webster]
     2. A treatise on this science.
        [1913 Webster]
     Analytical geometry, or Co["o]rdinate geometry, that
        branch of mathematical analysis which has for its object
        the analytical investigation of the relations and
        properties of geometrical magnitudes.
     Descriptive geometry, that part of geometry which treats of
        the graphic solution of all problems involving three
     Elementary geometry, that part of geometry which treats of
        the simple properties of straight lines, circles, plane
        surface, solids bounded by plane surfaces, the sphere, the
        cylinder, and the right cone.
     Higher geometry, that pert of geometry which treats of
        those properties of straight lines, circles, etc., which
        are less simple in their relations, and of curves and
        surfaces of the second and higher degrees.
        [1913 Webster]
