I'd suggest rotating through 720 degrees, just to be certain.
Which way, cw or ccw? Facing north or south ?
You gotta be more specific in things like this.

MARK!
(though personally, I'd multiply by the square root of negative 1, and
rotate everything 90 degrees in post-processing)
I'd go even further and rotate everything 360 degrees. Just in case.
That's still not enough. There are a few esoteric situations where it is
possible to distinguish between odd and even multiples of 360 degrees of
rotation. I'd suggest rotating through 720 degrees, just to be certain.
