A parallelogram is transformed according to the rule (x, y) → (x, y). Which is another way to state the transformation?

Question

R0, 90°
R0, 180°
R0, 270°
R0, 360°

Answer 1

The transformation rule \((x, y) \rightarrow (x, y)\) indicates that each point in the parallelogram remains unchanged. This transformation can be described as a rotation about the origin by 0 degrees or a complete rotation of 360 degrees.

Thus, another way to state the transformation is:

R0, 360°

Any rotation that results in the same configuration of the parallelogram can be represented, such as R0, 360°, or just stating that there is no rotation (or a rotation of 0°).
