Mirror Reflection
Mirror Reflection Direction problems involve determining how a direction appears when viewed in a mirror. A mirror reverses left and right horizontally (horizontal mirror) or top and bottom vertically (vertical mirror/water reflection). These problems test spatial visualization and understanding of reflection symmetry.

Prerequisites
How to Solve Mirror Reflection Problems
Step 1: Identify the mirror orientation (horizontal/vertical)
Step 2: For horizontal mirror (left-right reversal): N↔N, E↔W, S↔S, NE↔NW, SE↔SW
Step 3: For vertical mirror (water reflection): N↔S, E↔E, W↔W, NE↔SE, NW↔SW
Step 4: Apply the appropriate mapping to the given direction
Step 5: For a person facing a direction, determine the direction the reflection faces
Step 6: Consider the mirror position relative to the person (in front, left, right, behind)
Step 7: Express the reflected direction
Example Problem
Example: A person faces North and looks into a horizontal mirror placed in front of him. Which direction does his reflection appear to face? Solution: Step 1: Mirror = horizontal (left-right reversal), placed in front Step 2: When facing North, the reflection faces the opposite direction (South) Step 3: Because the mirror reverses front-back as well as left-right Step 4: Therefore, the reflection faces South Answer: South
Pro Tips & Tricks
- Mirror in front: reflection faces opposite direction (N↔S, E↔W)
- Mirror on left: reflection faces direction 90° anticlockwise from your facing
- Mirror on right: reflection faces direction 90° clockwise from your facing
- Mirror behind: reflection faces same direction as you
- Water reflection (vertical mirror): reverses top-bottom, N↔S, E↔E, W↔W
- The word 'AMBULANCE' written backwards is readable in rear-view mirrors
