Which of the given alphabet cannot be divided into symmetrical halves, along the given dotted lines?
All the letters are divided using a vertical line.
If we look closely, after dividing the alphabet 'T' and 'Y', the halves of the letters can overlap each other when folded along the given line. Both halves are mirror halves.
So, these are symmetric about the line.
But when we observe the alphabet, 'N', 'E' and 'R', the halves do not have the same features like design, length, etc. Both halves are not mirror halves and they can’t exactly overlap each other.
Hence, these are not symmetrical.
So, letters 'N', 'E' and 'R' are asymmetric about the line.
Hence, "Alphabet 'E', 'N' and 'R'", is the correct option.
