Question

# Let A be a square matrix. Then which of the following is not a symmetric matrix -

- A +
- A
- A
- A –

## The correct answer is: A

### we are asked to find which of the given options is not a symmetric matrix

A is a square matrix (A - A')'

= A' - (A')'

=A' - A

hence it is not a symmetric matrix

Therefore we find that A -A' is not a symmetric matrix
