triangulation

triangulation [trahy-ang-gyuh-ley-shuh n] ExamplesWord Origin noun Surveying, Navigation.

  1. a technique for establishing the distance between any two points, or the relative position of two or more points, by using such points as vertices of a triangle or series of triangles, such that each triangle has a side of known or measurable length (base or base line) that permits the size of the angles of the triangle and the length of its other two sides to be established by observations taken either upon or from the two ends of the base line.
  2. the triangles thus formed and measured.

Origin of triangulation 1810–20; Medieval Latin triangulātiōn- (stem of triangulātiō) the making of triangles. See triangulate, -ion Examples from the Web for triangulation Contemporary Examples of triangulation

    triangulation in Science triangulation [trī-ăng′gyə-lā′shən]

    1. A method of determining the relative positions of points in space by measuring the distances, and sometimes angles, between those points and other reference points whose positions are known. Triangulation often involves the use of trigonometry. It is commonly used in the navigation of aircraft and boats, and is the method used in the Global Positioning System , in which the reference points are satellites.
