This isn't really homework, but we are doing it in Geometry, and I'm having some trouble understanding it for some reason.
I know how easy it is supposed to 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)?
