A bearing (the angle in degrees measured clockwise from north) or course heading begins on the North Pole (correspond to initial side)
Unlike in standard position, Bearings cannot be
Bearing - the angle in degrees measured clockwise from north
Heading -(the direction) the angle between north and the direction that is chosen
Like the standard position, what quadrant the final direction (corresponding to terminal side) is located at, is the quadrant that it live.

“However, in navigation, angles are measured using headings. A bearing is also measured from due north.
If I say a boat is heading in the direction 150°, then you measure from due north, 150° clockwise. See the image below:”
