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?
$45^\circ$
$90^\circ$
$180^\circ$
$360^\circ$
Solution
Turning from North to East represents a quarter turn clockwise, which corresponds to a $90^\circ$ rotation.
