This isn't really homework, but we are doing it in Geometry, and I'm having some trouble understanding it for some reason.(adsbygoogle = window.adsbygoogle || []).push({});

I know how easy it issupposedto be, but I'm having problems solving.

More specifically, with rotations.

Like say they give me coordinates on a coordinate plane, (x,y). 3 of these coordinates are given to make a quadrilateral.

And let's say they ask us to rotate it clockwise 90 and 180 degrees.

Counter-clockwise 260 degrees.

Is there anyway I can solve for that without moving my book around and making pencil marks all over my textbook?

Isn't the transformation suppose to be: (x,y) ---> (-y,x)?
