'Clockwise' means that you turn (rotate) in the same direction as the hands of the clock turn. 180o = two lots of 90o or a half turn
|
'Anticlockwise' means that you turn (rotate) in the opposite direction to which the hands of the clock turn. 180o = two lots of 90o or a half turn

135o = three lots of 45o or three-eighths of a rotation (turn): 45o is an eighth of a turn
|
225o = five lots of 45o or five-eighths of a rotation (turn): 45o is an eighth of a turn

It doesn't make any difference whether you turn clockwise or anticlockwise because you are making a whole turn; this means that you will always end up facing the same way no matter which way you turn

Neil turns through 225o (= five lots of 45o) and ends up facing South. Sergei will have to turn clockwise through 45o (an eighth of a turn) or anticlockwise through 315o (seven-eighths of a turn)

Sarah turns three-eighths of a rotation and ends up facing NW. Wilma must turn either 315o anticlockwise or 45o clockwise

You would do yourself a favour by learning the points of the compass!
