Thanks, Terry, I'm so embarrassed...It's so simple : ( I guess polar coordinate that's very helpful for rotating... )

"I guess polar coordinate that's very helpful for rotating..."

Provided that you want to rotate around the origin.

If you want to rotate around another point than origin, then you're up for a challenge.

Success!
