A boy and a girl are facing each other. If the boy is standing at the north-west direction of the girl, in which direction is the girl to the boy?
- ANorth
- BSouth
- CEast
- DSouth-east
Solution & Step-by-step Explanation
Direction vectors are completely symmetric and diametrically opposite to each other.
The boy is located at the North-West position relative to the girl's center.
Therefore, when looking from the boy's viewpoint, the girl's direction will be the exact opposite of North-West.
Opposite mappings:
Opposite of North → South
Opposite of West → East
Thus, the exact opposite of North-West is South-East.
The girl is in the South-East direction relative to the boy.
