Triangulation (disambiguation)
Triangulation (surveying) refers to measurement by using triangles. Triangulation may also refer to:
Mathematics and computer science
- Subdivisions of spaces into triangles or higher dimensional simplices:
- In graph theory:
- Maximal planar graphs are sometimes called triangulations, and a maximal planar supergraph of a graph G may be called a triangulation of G.
- Chordal graphs are sometimes called triangulated graphs. As in the planar case, if a graph G is a subgraph of a chordal graph H, H may be called a triangulation of G.
- A triangulated category is a category defined by a set of axioms involving triangles of arrows.
- Triangulation (computer vision) is the computation of a 3D point given its projection onto two, or more, images.
- In linear algebra, triangulation is a process of finding an upper triangular matrix similar to given a matrix. See Schur triangulation.
- Mobile phone tracking uses triangulation, (actually, trilateration), to calculate the location of the handset.
Other fields
- Triangulation (actuary), a model that actuaries use to predict future costs of past and current claims obligations.
- Triangulation (chess), a maneuver in which one player moves a piece (often a king) in a triangular pattern in order to force the opponent to make a weakening move
- Triangulation (psychology), situation in which one person interacts with another person via an intermediary third person.
- Triangulation (politics), the act of a candidate presenting his or her ideology as "above and between" the left and right side of the political spectrum
- Triangulation (social science), the use of multiple cross-checked sources and methodology
