The ink nubs create a space between the protractor triangle and the ground to prevent the lines from smudging.
The navigation triangle can be used to measure distances directly from a map. Make sure that you use the correct scale for the map. For the common scales 1:500,000 and 1:200,000, use the respective scale directly. For other scales, the distances can be easily calculated by multiplication or division.
