   {Trigonometrical survey}, a survey of a portion of country by
      measuring a single base, and connecting it with various
      points in the tract surveyed by a series of triangles, the
      angles of which are carefully measured, the relative
      positions and distances of all parts being computed from
      these data.

   {Trigonometrical lines}, lines which are employed in solving
      the different cases of plane and spherical trigonometry,
      as sines, tangents, secants, and the like. These lines, or
