Question

The number of capital letters of the English alphabets having only horizontal line of symmetry is:-
A.5
B.4
C.3
D.1

Answer 1

Hint: Before solving this question, we must know about Symmetry, symmetrical objects and symmetrical lines.
Symmetry: Symmetry means that one shape is exactly like another one when you move it in some way, for example; turning or flipping the object.
Symmetrical Objects: An object is symmetrical when it is the same on both the sides. A shape is symmetrical if a central dividing line can be drawn on it, to show that both the sides of the shape are exactly the same.
Symmetrical Line: The symmetrical line is the imaginary line that passes through the center of a shape or object and divides it into identical parts. It is also known as the line of symmetry.

Complete step-by-step answer:
Let us now solve this question.
Some English alphabets have a line of symmetry and some of them do not have one.
Some have no line of symmetry, some of them have only one and some have infinity.
Here, we are going to discuss the alphabets that have just one line of symmetry, and that too horizontal.
Here are the English alphabets.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
We can see that only a few of these alphabets have a single, horizontal line of symmetry. They are mentioned below:-
B
C
D
E
K
So, there are only 5 capital English alphabets having a single and horizontal line of symmetry. They are B, C, D, E, and K.
Here is the proof:-

So, the correct option for this question is (a) 5.

Note: The alphabet ‘O’ has an infinity line of symmetry.
Infinity means that the number of lines of the letter O cannot be counted.

One can draw infinity lines of symmetry on the letter ‘O’.
