What does triangulating mean?
Triangulating means using more than one point of reference, measurement, or source of evidence to establish a more dependable conclusion. In its technical sense, the process involves determining an unknown position or distance by calculating from measurements taken at known locations; the term comes from geometry, where triangles make it possible to infer the position of a point from angles and distances. In everyday and professional figurative use, triangulating means comparing independent sources or lines of evidence to verify a finding, narrow down an answer, or reduce the influence of error and bias. The expression is especially common in journalism, investigation, research, navigation, and surveying. It conveys a careful, methodical process rather than a casual guess, and it implies that agreement among independent references gives the result greater reliability. The word is useful because it captures both precise measurement and the broader idea of checking a claim against multiple perspectives.
verbTriangulating is determining the position, distance, or direction of something by measuring from multiple known points. In figurative use, it means checking or establishing a conclusion by combining information from independent sources.
- Using measurements from known points to determine the position, distance, or direction of something.
- Combining independent pieces of information to verify or establish a conclusion.
"The investigators triangulated the suspect's location by comparing reports from three witnesses."
"By triangulating the signal from three different receivers, the team was able to locate the transmitter."
"The report reached a reliable conclusion by triangulating evidence from financial records, interviews, and travel data."
Three points can reveal a position: triangulation turns angles and distances into a map of what is out of sight.

Etymology of triangulating
The word comes through English triangulate, from Latin triangulare, “to make into a triangle” or “to measure by triangles.” Its roots are Latin tri-, meaning “three,” and the related angulus, meaning “angle,” with the underlying geometric noun triangulum meaning “triangle.” The same root appears in cognates and related forms such as triangle, triangular, and trigonometry, all of which connect the word with three-cornered figures and the measurement of angles.
