IPA: //traɪˈæŋɡjʊleɪʃən//
KK: /traɪˈæŋɡjʊleɪʃən/
A method used in surveying and navigation to determine the location of a point by forming triangles with known points.
The surveyor used triangulation to accurately map the area.
Triangulation is formed from "tri-" (meaning three) and "angulus" (meaning angle) combined with the suffix "-ation" (indicating a process or action). The term refers to the process of determining the location of a point by forming triangles to it from known points.
Think of 'three' ('tri-') angles ('angulus') coming together in a process ('-ation') to find a location. This helps you remember that triangulation is about using three angles to determine a position.
