### Princeton's WordNet

triangulation(noun)

a trigonometric method of determining the position of a fixed point from the angles to it from two fixed points a known distance apart; useful in navigation

triangulation(noun)

a method of surveying; the area is divided into triangles and the length of one side and its angles with the other two are measured, then the lengths of the other sides can be calculated

### Wiktionary

triangulation(Noun)

A technique in surveying in which distances and directions are estimated from an accurately measured baseline and the principles of trigonometry

triangulation(Noun)

The network of triangles, so obtained, that are the basis of a map or chart

triangulation(Noun)

In navigation or seismology, a process by which an unknown location is found using three known distances from known locations.

triangulation(Noun)

A delaying move in which the king moves in a triangular path in order to force the advance of a pawn.

triangulation(Noun)

The use of three (or more) researchers to interview the same people or to evaluate the same evidence to reduce the impact of individual bias.

### Webster Dictionary

Triangulation(noun)

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 connected by them

### Freebase

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. The point can then be fixed as the third point of a triangle with one known side and two known angles. Triangulation can also refer to the accurate surveying of systems of very large triangles, called triangulation networks. This followed from the work of Willebrord Snell in 1615–17, who showed how a point could be located from the angles subtended from three known points, but measured at the new unknown point rather than the previously fixed points, a problem called resectioning. Surveying error is minimized if a mesh of triangles at the largest appropriate scale is established first. Points inside the triangles can all then be accurately located with reference to it. Such triangulation methods were used for accurate large-scale land surveying until the rise of global navigation satellite systems in the 1980s.
