Dear Student,

Please find below the solution to the asked query:

We know : A shape has Rotational Symmetry when it still looks the same after a rotation.

And

How many times it matches when we go once around is called the Order.

So, In 360$°$ turn square is looks same as itself four times ( After each 90$°$ turn ) .

That's why we have order of symmetry of square is 4  .
