- North
Show the answer and the worked solution
Correct answer: A. North-east
Worked solution
- North-west is at 315°.
- A 90° clockwise turn gives 315 + 90 = 405°, which is the same as 45°.
- That is north-east.
Answer: North-east.
The idea
Use degrees for the diagonal directions: NE 45°, SE 135°, SW 225°, NW 315°. Subtract 360 whenever the total passes a full turn.
Shortcut. A 90° clockwise turn moves each diagonal one place along NE → SE → SW → NW → NE, so NW becomes NE.
Common trap. "South-west" — turning 90° anticlockwise instead: 315° − 90° = 225°, south-west.
