Question

How many of the alphabets have exactly one line of symmetry?
A ,B, C, D, E, F, G, H, I, J, K, L, M, N, O .

Answer 1

Hint: Given are the English alphabets. We have to find the letters that are either symmetrical vertically or horizontally. So that is only one line of symmetry. A letter can have more than one line of symmetry but we will filter only those that have only one line of symmetry.

Complete step by step solution:
Let’s check the alphabets one by one.

Thus there are 8 letters that are having only 1 line of symmetry.

Note: Note that, line of symmetry is like a mirror. This line should divide the letter in exactly two halves. In the letters H and I there are two lines because these letters can be divided in exactly two halves by vertically as well as horizontally. Whereas for letter F,G,J and L there is no line since the letter is not at all symmetrical.
In the case of letter N it looks but not symmetrical either horizontally or vertically. If the folds are done it won't overlap.
