Question

Find out the letters of English alphabet or any other language known to you in which the image formed in a plane mirror appears exactly like the letter itself. Discuss your findings.

Answer 1

Applying Lateral Symmetry:

1. $A,H,I,M,O,T,U,V,W,$ and $X$ are the letters that form the same image as the letter is.
2. These letters are said to be in lateral symmetry.
3. Reflection through a plane mirror causes lateral inversion to the image.
4. So, no change will be observed after these letters are reflected on a plane mirror.
5. On the other hand, the letter, $B$ is not laterally symmetric.
6. So, it will undergo lateral inversion and the image will appear different from the object.
