The #'s are the circles you should shade in.
That's the answer. No line symmetry whatsoever, but it has 90 degree rotational symmetry.
I have a diagram of 25 congruent circles in a 5 x 5 pattern, but all touching, somewhat like this:

Just forget the spaces between the lines, imagine they are all bunched up together to form a perfect square. The question says I am to shade at least one circle so the figure has rotational symmetry of 90 degrees, but no line of symmetry. After looking at this, I fail to see how it's possible, but obviously it must be. Thank you all for your time and answers

Hello,
As Jhevon said, it seems there is no 90° rotational symmetry. Plus, there is a line of symmetry :

Another possibility is to shade circles so that they form a swastika.Code:OOO#O #OOOO OOOOO OOOO# O#OOO
