The term 'reduced bearing' (RB) differs from 'whole circle bearing' (WCB) in that:
Choose the correct answer
WCB is measured anticlockwise; RB clockwise
RB is measured 0–90° from N or S toward E or W (quadrant notation); WCB is 0–360° clockwise from N
Both are identical
RB is measured only in southern hemisphere
Correct Answer
B. RB is measured 0–90° from N or S toward E or W (quadrant notation); WCB is 0–360° clockwise from N

WCB (azimuth): measured clockwise from North, 0° to 360°. RB (quadrant bearing): measured from North or South toward East or West, 0° to 90° in each quadrant (e.g., N45°E, S30°W). RB states both reference meridian and direction of measurement. WCB to RB conversion: NE (0–90°) RB = WCB; SE (90–180°) RB = 180°−WCB; etc.
