Triangulation (disambiguation)
# Triangulation (disambiguation)

Triangulation is the process of determining the location of a point by forming triangles to it from known points.

Triangulation may also refer to:

## Arts, entertainment, and media

* 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 (TWiT.tv), an interview podcast
* Triangulation (novel), a 1999 novel by Phil Whitaker

## Mathematics and technology

### Graph theory

* Plane triangulation, and a maximal planar supergraph of a graph G may be called a triangulation of G
* Triangulated graph, and a chordal completion of a graph G may be called a triangulation of G

### Spatial subdivisions

* Triangulation (geometry), division of the Euclidean plane into triangles and of Euclidean spaces into simplices
* Triangulation (topology), generalizations to topological spaces other than $R^d$
* Point-set triangulation, division of the convex hull of a point set into triangles using only that set as triangle vertices
* Polygon triangulation, division of a polygon into triangles
* Surface triangulation, division of a surface into triangles

### Other uses in mathematics and technology

* Triangulation (computer vision), the computation of a 3D point given its projection onto two, or more, images
* Triangulation (surveying), a process used in surveying to determine unknown distances, angles and positions from those that are known
* Mobile phone tracking, a process which uses triangulation (actually, trilateration) to calculate the location of the handset
* Schur triangulation, a process of finding an upper triangular matrix similar to a given matrix
* Stellar triangulation, a method of geodesy which uses cosmic instead of terrestrial targets
* Triangulated category, a category defined by a set of axioms involving triangles of arrows
* Triangulation station, a fixed surveying station

## Psychology and social sciences

* Triangulation (psychology), situation in which one person interacts with another person via an intermediary third person
* Triangulation (social science), the use of multiple cross-checked sources and methodology
* Karpman drama triangle, resulting from "triangulation", a psychological and social model of human interaction – typically among the roles of persecutor, victim, and rescuer

## Other uses

* 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
