Difficulty: Easy
Correct Answer: East
Explanation:
Introduction / Context:
The goal is to track the facing after a sequence of turns from an initial heading. Only the facing matters; the distances are irrelevant.
Given Data / Assumptions:
Concept / Approach:
Apply successive 90° rotations relative to the current heading, not the original one. A quick sketch or a mental compass cycle helps avoid errors.
Step-by-Step Solution:
Verification / Alternative check:
Think of left as -90° and right as +90°. Starting at North, the net rotation is (-90 + 90 + 90) = +90° → East.
Why Other Options Are Wrong:
Common Pitfalls:
Losing track after the second turn, or applying turns relative to the initial facing instead of the current one.
Final Answer:
East
