Shape Mirror - Medium

Shape Mirror Medium problems involve composite shapes made of multiple components (e.g., a semicircle on the left and a triangle on the right). The mirror swaps the positions of the left and right components and reverses each component's orientation.

Introduction to Shape Mirror - Medium

Shape Mirror Medium problems involve composite shapes made of multiple components (e.g., a semicircle on the left and a triangle on the right). The mirror swaps the positions of the left and right components and reverses each component's orientation.

Prerequisites

Basic shape mirror concepts Left-right position swapping Composite shape analysis Component-wise reflection
Why This Matters: Shape Mirror Medium problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test understanding of composite shape reflection.

How to Solve Shape Mirror - Medium Problems

1

Step 1: Identify all components of the shape and their positions

2

Step 2: In a vertical mirror, left and right positions swap

3

Step 3: Each component's own orientation reverses (if asymmetric)

4

Step 4: The overall shape is the mirror of the original

5

Step 5: The distance from the mirror line remains the same

6

Step 6: Reconstruct the mirrored composite shape

7

Step 7: Answer with the description of the mirrored shape

Pro Strategy: Treat each component separately. Swap left and right positions, and mirror each component individually. The overall arrangement is the mirror image.

Example Problem

Example: What is the mirror image of a shape with a semicircle on the left and a triangle on the right? Solution: Step 1: Components: left semicircle, right triangle Step 2: Mirror swaps left and right Step 3: Semicircle on right, triangle on left Step 4: Each component's orientation reverses as needed Answer: Semicircle on right, triangle on left

Pro Tips & Tricks

  • Left component becomes right component after mirror
  • Right component becomes left component after mirror
  • The mirror line is vertical, so top/bottom positions remain
  • The distance from the mirror line is preserved
  • Composite shapes require component-wise analysis
  • The mirrored shape may look completely different from the original

Shortcut Methods to Solve Faster

Left ↔ Right (positions swap)
Each component's mirror is applied individually
The overall shape is the mirror of the original
Symmetric components (circle, square) look the same after mirror

Common Mistakes to Avoid

Only swapping positions without mirroring each component
Forgetting that asymmetric components also reverse orientation
Not maintaining correct distances from mirror line
Confusing vertical mirror with horizontal mirror
