If a person is facing north and takes two consecutive right turns, what…

Concept: In direction-sense reasoning, the four principal directions North, East, South, and West lie 90 degrees apart in a clockwise cycle. Viewed from above, a right turn rotates the observer 90 degrees clockwise from the current facing, while a left turn rotates 90 degrees anticlockwise. Multiple turns combine by adding their signed rotations (clockwise positive), and the total rotation is then mapped back onto this compass cycle.

1. Start facing North, taken as a 0 degree reference point on the compass cycle.

2. First right turn: rotate 90 degrees clockwise from North (0 degrees), giving 90 degrees, which corresponds to East.

3. Second right turn: rotate another 90 degrees clockwise from East (90 degrees), giving 180 degrees, which corresponds to South.

Cross-check: A rotation of exactly 180 degrees always points to the direction diametrically opposite the starting direction. The direction opposite North is South, which confirms the result independently.

Result: after two consecutive right turns from North, the person faces South.
