Triangulation is the surveying technique in which unknown distances between stations may be determined by trigometric applications of a triangle or triangles. In triangulation, one side called the baseline and at least two interior angles of the triangle must be measured. When all three interior angles are measured, accuracy of the calculated distances is increased and a check is provided against any measurement error.
