In an evaluation, triangulation is an attempt to get a fix on a phenomenon or measurement by approaching it via several (three or more) independent routes This effort provides redundant measurement
A method of surveying in which the stations are points on the ground at the vertices of a chain or network of triangles The angles of the triangles are measured instrumentally and the sides are derived by computation from selected sides or bases, the lengths of which are obtained by direct measurement on the ground or by computation from other triangles
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
In a dome context, triangulation is used to mean the process of subdividing a triangle into smaller triangles So if the base figure (usually an icosahedron) has large triangular faces, then triangulation involves subdividing each of the icosahedron's triangular faces into a grid of smaller triangles (Note: triangulation is the term I've always used, if anybody knows a more accepted term for this concept, please let me know!)

Using multiple methods and/or data sources to study the same phenomenon The idea here is for the weaknesses in any one method to be compensated for by the strengths of another The researcher addresses the issue from different methodological positions, rather like taking photographs of the same subject from different angles to reveal a more valid picture of what the object actually looks like
A method of surveying in the location of an object may be calculated from the known locations of two other objects Creating a triangle from the three items, the angles and sides of the triangle can be measured and the location of the unknown object is calculated algebraically
the use of three (or more) sources of information to derive and substantiate an assessment or conclusion
A process of cross-checking and cross-validating by talking with and referring to various sources The "triangle" refers to simultaneous use of (1) perception, (2) validation and (3) documentation It is the verification of information by using the same topic of investigation in three ways, i e in terms of composition of team, techniques applied and sources of information By combining multiple data-sources, methods, analyses or theories, evaluators hope to overcome the bias that comes from single informants, single-methods, single observer or single theory studies
the method in surveying of making measurements and using trigonometry to find where places are located on the earth's surface using points whose exact location is known
The lengthy process of pinning down a caller's location using radio receivers, a compass and a map
Technique for organizing a structure or system in triangular form (see Triangulated System)
