Non-Verbal Reasoning: Mirror Image

In non-verbal reasoning, mirror image is a common type of question where you are asked to identify how an object, shape, or figure would appear if reflected in a mirror. The reflection occurs in the vertical plane (like looking at an image in a mirror placed on the left or right side of the object) or in the horizontal plane (like a reflection in a mirror placed above or below the object). This type of question tests your ability to visualize and mentally rotate images.

Key Concepts in Mirror Image

1. Vertical Mirror Reflection:

   • The figure or object is reflected in a vertical plane, meaning the mirror is placed on the left or right side of the object.
   • The left side of the object becomes the right in the mirror, and vice versa.
   • The top and bottom of the object remain unchanged.

2. Horizontal Mirror Reflection:

   • The figure or object is reflected in a horizontal plane, meaning the mirror is placed above or below the object.
   • The top of the object becomes the bottom, and vice versa.
   • The left and right sides of the object remain unchanged.

Steps to Solve Mirror Image Questions

1. Understand the Figure:

   • Look at the given figure carefully. Observe all its parts (lines, angles, shapes, etc.), keeping in mind whether it is being reflected horizontally or vertically.

2. Visualize the Mirror:

   • Imagine where the mirror is placed (either on the left, right, top, or bottom) of the object.
   • For vertical mirror reflection, swap the left and right sides.
   • For horizontal mirror reflection, swap the top and bottom.

3. Apply the Transformation:

   • Reflect the image in your mind and then look at the options provided. The correct option will match the transformed (mirrored) image.

4. Check Details:

   • Ensure the overall shape, symmetry, and direction of elements match the expected transformation.

Example of Vertical Mirror Image

Original Image:

This is a simple triangle with a line through the middle. If a vertical mirror is placed on the right side, the left and right parts will be flipped.

Mirror Image (Vertical Reflection):

Explanation:

• The left side of the triangle becomes the right side, and the right side becomes the left side. However, the top and bottom remain unchanged.

Example of Horizontal Mirror Image

Original Image:

This is a rectangle. If a horizontal mirror is placed below the rectangle, the top and bottom will be flipped.

Mirror Image (Horizontal Reflection):

Explanation:

• The top and bottom of the figure swap places, but the left and right remain the same.

Important Points to Remember:

1. Symmetry: Symmetrical objects (e.g., circles, squares, etc.) will look the same when reflected in a mirror.
2. Complex Figures: For more complex figures, break them into simple parts (lines, circles, etc.) and reflect them individually.
3. Direction and Rotation: Pay attention to the direction of any lines or shapes; these may change depending on the position of the mirror.
4. Details: Every detail matters – even small marks, patterns, and angles can affect the mirrored image.

Practice Question 1:

Original Image:

If the figure is reflected in a vertical mirror, what will it look like?

• A)

• B)

• C)

• D)

Answer:

• B) will be the correct option as the shape is flipped along the vertical axis.

Practice Question 2:

Original Image:

If the figure is reflected in a horizontal mirror, what will it look like?

• A)

• B)

• C)

• D)

Answer:

• A) will be the correct answer, as the top and bottom are flipped in a horizontal reflection.

Conclusion

Mirror image questions assess your ability to mentally manipulate shapes and objects. By practicing these types of problems, you can develop the skills to recognize how figures change when reflected. With regular practice, you can improve your ability to quickly visualize and solve these types of questions.
