Triangulation Calculator

Locate a point's distance using a baseline and two angles.

Distance from A 81.521

Distance from B 92.16

Formula: Law of sines with γ = 180° − α − β

Step-by-step with your numbers:

1. Values used:

2. Baseline length = 100

3. Angle at A = 60 °

4. Angle at B = 50 °

6. Distance from A = 81.521

7. Distance from B = 92.16

Did we solve your problem today?

Triangulation finds an unknown point by measuring two angles from the ends of a known baseline.

The math behind it

The third angle is γ = 180° − α − β. The law of sines then gives each distance from the baseline endpoints.

Baseline 100, angles 60° and 50° → distances ≈ 84.8 and 96.4.

Where is triangulation used?

Surveying, navigation, GPS and astronomy to find positions and distances.
