In the English alphabet, the letters A, H, I, M, O, T, U, V, W, X, and Y will appear exactly the same when viewed in a mirror. This is due to their symmetry, where the image formed is a reflection of the letter itself.
Explanation:
Lateral Symmetry:
These letters have a vertical line of symmetry, meaning they look the same when flipped horizontally.
Plane Mirror Reflection:
A plane mirror creates a lateral inversion of the image, which means it flips the image horizontally.
Combined Effect:
The mirror’s lateral inversion perfectly aligns with the letter’s vertical symmetry, resulting in an image that appears identical to the original letter.
In simpler terms: Imagine drawing a line down the middle of each letter. If the two halves match perfectly (like with A or O), then the mirror image will still be the same.
