When a point it rotated, it must be rotated across a center.
The mapping rule of 270 degrees clockwise rotation is:[tex]\mathbf{(x,y) \to (-y,x)}[/tex]
Assume that a coordinate point is (x,y).
A point rotated at 270 degrees clockwise, would land on the same point as a rotation of 90 degrees counter-clockwise
The rule of 90 degrees counter-clockwise is
[tex]\mathbf{(x,y) \to (-y,x)}[/tex]
Hence, the mapping rule of 270 degrees clockwise is:
[tex]\mathbf{(x,y) \to (-y,x)}[/tex]
