What method is used to locate an unknown point by determining where the azimuths from at least two known points meet?

The method used to locate an unknown point by determining where the azimuths from at least two known points meet is referred to as intersection. This technique involves taking bearings (or azimuths) from two or more fixed, known locations and following those directional lines to their point of convergence, which indicates the location of the unknown point.

In practice, this is commonly utilized in navigation and surveying, where accurately plotting a position is essential. The concept of intersection relies heavily on the ability to pinpoint the known locations and accurately measure the azimuths. Once these lines meet, the position can be marked, providing a practical application of geometric principles in real-world settings.

The methods referred to in the other options—such as resection, navigation, and localization—are related but do not fit the specific scenario described in the question as precisely as intersection does. Resection typically involves determining a position using known locations and measurements but focuses on determining the observer’s location rather than finding an unknown point specifically through azimuth convergence.
