Question

# If A = 0, then is -

- orthogonal matrix
- symmetric matrix
- skew- symmetric matrix
- triangular matrix

Hint:

### we know that if A = A' Then A = A' is called symmetric matrix

## The correct answer is: symmetric matrix

### We are given that A-A'=0 then we are asked to find A'

Therefore we find that it is a symmetric matrix
