Consider the standard compass directions measured clockwise from North:
North = 0°
North-East = 45°
East = 90°
South-East = 135°
South = 180°
South-West = 225°
West = 270°
North-West = 315°
Analyzing the given transformations:
North-East (45°) becomes North (0°)
Change: 45°−45°=0°
South-East (135°) becomes East (90°)
Change: 135°−45°=90°
The pattern shows a rotation of 45° counter-clockwise (subtracting 45° from each direction).
Applying this transformation to West:
West is at 270°
After the transformation: 270°−45°=225°
The direction at 225° is South-West.
Therefore, West becomes South-West.
The answer is Option 1.
