okay now i have 12?

OpenStudy (anonymous):

am i right?

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

Order of rotational symmetry depends upon the number of equal sides that a regular polygon has. is the definition so i am confused seriously

OpenStudy (anonymous):

omg thank you :D

hero (hero):

Basically order of rotation asks "How many times do I have to rotate it to get it back to its original position" You have to rotate it 4 times to get it back to its original position, therefore, the order of rotation is 4

OpenStudy (anonymous):

okay thanks

OpenStudy (anonymous):

it was wrong

hero (hero):

That's because the order of rotation is 2. Sorry, I wasn't looking closely enough at the pic.

hero (hero):

You only need to rotate it twice to get it back to original position. Agreed?

hero (hero):

I apologize. When I first looked at it, the bottom portion appeared to be a different color, but when I actually opened the file, I realize that it was all the same color.
