Answer:

D) R0 , 360°


Explanation:

We are given that the rotation is:

(x,y) --------> (x,y)

This means that the point is rotated back into its original position.

This means that full rotation occurred.

Since the full rotation is 360°, therefore, the correct answer is D


For the other options:

Rotation 90° gives:

(x,y) ----------> (-y,x)


Rotation 180° gives:

(x,y) ----------> (-x,-y)


Rotation 270° gives:

(x,y) ---------> (y,-x)


Hope this helps :)
