     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
        dimensions.
  
     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]

From The Collaborative International Dictionary of English v.0.48 :

  Descriptive \De*scrip"tive\, a. [L. descriptivus: cf. F.
     descriptif.]

     descriptive of the age.

     Descriptive anatomy, that part of anatomy which treats of
        the forms and relations of parts, but not of their
        textures.
  
     Descriptive geometry, that branch of geometry. which treats
        of the graphic solution of problems involving three
        dimensions, by means of projections upon auxiliary planes.
        --Davies & Peck (Math. Dict. ) -- De*scrip"tive*ly, adv.
        -- De*scrip"tive*ness, n.
        [1913 Webster]

From WordNet (r) 3.0 (2006) :

  descriptive geometry
      n 1: the geometry of properties that remain invariant under
           projection [syn: projective geometry, descriptive
           geometry]
