What technique is employed to determine your position on a map using two plotted points?

Resection using back azimuths is the technique that allows an individual to determine their position on a map by utilizing two plotted points. This method involves taking bearings to known landmarks or points, then determining the back azimuth (the reverse direction) of those bearings. By plotting these back azimuth lines on the map from the known points to where they intersect, you can accurately pinpoint your position. This is particularly useful in navigation because it enables a traveler to establish their location without needing to know exactly where they are starting from, relying instead on recognizable landmarks.

In contrast, triangulation, while a useful technique for determining position, typically requires three known points rather than two. Dead reckoning involves estimating your current position based on a previously determined position, accounting for speed and time, which is less precise than the method in question. Land navigation encompasses various skills and techniques for moving from one point to another but does not specifically focus on the technique of using plotted points to determine one's exact location like resection does.
