In case it is a 270º Counter-clockwise rotation:
P'(3,-3), Q'(5,-5), R'(6,-3)
In case it is a 270º Clockwise rotation:
P'(-3, 3), Q'(-5,5), R'(-6,3)
1) Since in this case, there is a 270º rotation about the origin then we can write out the following:
As there is no mention of the direction then we'll do it for both cases.
2) For a 270º Counter-Clockwise rotation
Pre-image rule Image
P(3,3) (x,y)=(y,-x) P'(3,-3)
Q(5,5) Q'(5,-5)
R(3,6) R'(6,-3)
3) For a Clockwise Direction
Pre-image rule Image
P(3,3) (x,y)=(-y,x) P'(-3, 3)
Q(5,5) Q'(-5,5)
R(3,6) R'(-6,3)
