Front

What is the relationship between true bearing and quadrant bearing?

Back

True bearing is measured clockwise from North, while quadrant bearing is measured from the North or South towards the East or West.

What does a negative dot product indicate about two vectors?

Back

The vectors are pointing in opposite directions.
