There's another postulate you aren't considering, though. Only one
line can pass through any two points.

Since the two compasses each point toward a particular point, and the
other point is *the location of the compass*, given that you have a
map showing the "homing point" for both compasses, you can determine
your own location quite easily. It's called "Triangulation".
