--- Quote from: Dibss on May 13, 2010, 11:03:26 am ---from a website >>Is there Rotational Symmetry of Order 1? Not really! If a shape only matches itself once as you go around (ie it matches itself after one full rotation) there is really no symmetry at all, because the word "Symmetry" comes from syn- together and metron measure, and there can't be "together" if there is just one thing.)
from a different site >> "A" has got rotational symmetry of order 1. This is just a complicated why of saying that you can not turn "A" around to any other position so it looks the same.
So rotational symmetry order of 1 means NO rotational symmetry (we can't rotate it).
----does this mean that the first answer could be 1 OR 0 or what?
EDIT: shazizzle, looks like we both ended up at google for the same reason! haha :P

Okay, umm, this is for CIE to worry about.
