Triangulation Calculator

Locate an unknown point from a known baseline and two angles measured to it (classical surveying triangulation, law of sines).

Frequently Asked Questions

What is triangulation?

A method to find an unknown point from two known points (the baseline) and the angles measured from each to the unknown point. Uses the law of sines.

How accurate is it?

Accuracy depends on baseline length and angle measurement precision. Surveys with theodolites achieve sub-arcsecond precision.

Difference from trilateration?

Triangulation uses angles; trilateration uses distances. GPS is trilateration.
