# Symmetric & Skew Symmetric matrices

Last updated at April 4, 2019 by Teachoo

In a symmetric matrix,

A’ = A

And in a skew symmetric matrix

A’ = −A

Note:

*
Here matrix should be a square matrix

Let’s take some examples

For

Since A = A’

∴ A is a symmetric matrix

For

Therefore,

B’ = −B

So, B is a skew symmetric matrix

In a skew

symmetric

matrix, diagonal elements are

always 0.
