Prerequisites
How to Solve About Face Problems Problems
Step 1: Identify the current facing direction
Step 2: Recognize that 'About Face' means turn 180° (half circle)
Step 3: The new direction is exactly opposite to the current direction
Step 4: Use opposite direction mapping: N↔S, E↔W, NE↔SW, SE↔NW
Step 5: The final facing direction is the opposite of the starting direction
Step 6: If multiple commands are given, apply sequentially or calculate net rotation
Step 7: Answer with the new direction
Example Problem
Example: A soldier is facing West. He is commanded 'About Face'. Which direction is he now facing? Solution: Step 1: Starting direction = West Step 2: About Face = 180° turn Step 3: Opposite of West = East Step 4: Final direction = East Answer: East
Pro Tips & Tricks
- About Face = 180° turn = face the opposite direction
- Two About Faces = 360° = return to original direction
- About Face then Right Turn = from North → South → West (net 90° right from start)
- About Face then Left Turn = from North → South → East (net 90° left from start)
- In military drill, 'About Face' is a crisp 180° turn
- Also called 'reverse march', 'U-turn', or 'half turn'
