A scout stands facing directly toward Magnetic North as shown by his compass needle ($0^\circ$). If he turns to his right until he faces directly East, through what angle has he turned relative to the magnetic needle?
  1. $45^\circ$
  2. $90^\circ$
  3. $180^\circ$
  4. $360^\circ$

Solution

Turning from North to East represents a quarter turn clockwise, which corresponds to a $90^\circ$ rotation.
