The another way to state the transformation would be [tex](x,y)>(-x,-y)[/tex]
Solution:
Rotation about the origin at [tex]180^\circ[/tex]: [tex]R_{180^\circ}A \rightarrow O = R_{180^\circ} (x, y) \rightarrow (-x,-y)[/tex]
The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to [tex]180^\circ[/tex] about the origin.
So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of [tex]180^\circ[/tex].
Hence according to the representation, the expression would be [tex](x, y) \rightarrow (-x, -y)[/tex].
