triangulation
Quick Summary
Triangulation is a method used in navigation, surveying, and engineering to determine precise locations or directions. It relies on the principles of plane trigonometry, where knowing one side and two angles of a triangle allows for the calculation of all other sides and angles. A measured side serves as the baseline, and adjacent angles are measured using a device like a theodolite. By creating a series of connected triangles, distances and angles that are otherwise difficult to measure can be determined. This technique has ancient origins, with early forms used by civilizations like the Egyptians and Greeks.1
