### Triangulation

In trigonometry and geometry, triangulation is the process of determining the location of a point by measuring angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly (trilateration). The point can then be fixed as the third point of a triangle with one known side and two known angles...

### Triangulation

• (n.) The series or network of triangles into which the face of a country, or any portion of it, is divided in a trigonometrical survey; the operation of measuring the elements necessary to determine the triangles into which the country to be surveyed is supposed to be divided, and thus to fix the positions and distances of the several points...

### triangulation

(engineering) Technique used in frame structures to provide strength and support. When a force is applied to a triangular frame, two of its members stretch the third one, making it tense. This in turn pulls the other two members towards it, making the structure rigid and spreading the force be...

### triangulation

(surveying) Technique used in surveying to determine distances, using the properties of the triangle. To begin, surveyors measure a certain length exactly to provide a base line. From each end of this line they then measure the angle to a distant point, using a theodolite. They now have a tria...

### Triangulation

[chess] Triangulation is a tactic used in chess to put one`s opponent in zugzwang. That is, it is a tactic, the goal of which is to return to the initial position in such a way that one`s opponent is then forced to move first in the position, when it is a disadvantage for that player to move, e.g. he must abandon a blockade and let the othe...

[computer vision] For each triangulation method, it can be determined if this last relation is valid. If it is, it may be satisfied only for a subset of the projective transformations, for example, rigid or affine transformations. It turns out that xest lies exactly at the middle of the shortest line segment which joins the two projection l...

### Triangulation

[geometry] In geometry, a triangulation of a planar object is a subdivision into triangles, and by extension the subdivision of higher-dimension geometric objects into simplices. Triangulation of a three-dimensional volume would involve subdividing it into tetrahedra (`pyramids` of various shapes and sizes) packed together. In most instance...

[politics] Triangulation is the name given to the act of a political candidate presenting his or her ideology as being `above` and `between` the `left` and `right` sides (or `wings`) of a traditional (e.g. UK or US) democratic `political spectrum`. It involves adopting for oneself some of the ideas of one`s political opponent (or apparent o...

### Triangulation

[psychology] The term triangulation is most commonly used to express a situation in which one family member will not communicate directly with another family member, but will communicate with a third family member, which can lead to the third family member becoming part of the triangle.

[social science] In the social sciences, triangulation is often used to indicate that two (or more) methods are used in a study in order to check the results. `The concept of triangulation is borrowed from navigational and land surveying techniques that determine a single point in space with the convergence of measurements taken from two ot...
