Question

__________ and __________ are the capital letters of English alphabets that have one line of symmetry but they interchange to each other when rotated through $180°$.

• A. M
• B. W

Answer 1

Step 1: Define the line of symmetry.

A figure has line symmetry if a line can be drawn dividing the figure into two identical
parts. The line is called a line of symmetry.

Step 2: Find the capital letters of English alphabets that have one line of symmetry but they interchange to each other when rotated through $180°$

Hence M and W are the capital letters of English alphabets that have one line of symmetry but they interchange with each other when rotated through $180°$.
