Question

Which of the following capitol letters is a reflection image of itself across a horizontal line

M,N,O,P

Answer 1

Answer: Letter O

Draw a horizontal line through the middle of the letter O. We can reflect the top part over this line to have it land on the bottom part, and vice versa.

In contrast, the letter M for instance would flip to W, and vice versa.

The letter P would turn into b.
