Triangulation (disambiguation)

Look up triangulation in Wiktionary, the free dictionary.

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:
- Triangulation (geometry), division of the Euclidean plane into triangles and of Euclidean spaces into simplices
- Polygon triangulation, division of a polygon into triangles
- Point set triangulation, division of the convex hull of a point set into triangles using only that set as triangle vertices
- Triangulation (topology), generalizations to topological spaces other than R^d
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
- These two concepts come together in strangulated graphs, which include both maximal planar graphs and chordal graphs
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 a given matrix; see Schur triangulation
Mobile phone tracking uses triangulation (actually, trilateration) to calculate the location of the handset

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 (finance), a financial strategy whereby the relationship between three currencies is exploited
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 (psychology), situation in which one person interacts with another person via an intermediary third person
