Protractor

because Earth is a sphere (well not quite a perfect sphere, but close enough). And a sphere is a series of circles. Circles are measured in degrees of arc. Degrees allow any point on earth to be located by its two coordinates (lat. and long.) It is extremely awkward if not impossible to do that with miles of kilometers.

It's called protractor.
If you don't have one, you can print one, cut and laminate it.
