Answer 1

Assuming that there is an triangle ABC and it is rotated to create a new image, A'B'C', we can check each of the presented rules.

1° - (x,y) - (x,y)

In this rule, every X will stil be the same X after the change. And so will the Y. This rule does not bring any change at all.

2° - (x,y) - (y,x)

In this rule , the coordinates X will become Y, and vice versa. It will mirror the image through an x=y line. This is not a rotation!!!

3° - (x,y) - (-x,y)

In this rule, the value of each X will become -X, and Y will keep unchanged. This rule just mirror the image through Y-axis.

4° - (x,y) - (y,-x)

In this rule, every point will have the X-values becoming the Y-axis value, in the oposite sigh. And for the Y-values, it will just become the X-axis. In this rule, what we got is a clockwise rotation.
