360 degree clockwise rotation rule

A rotation of 360 degrees about the origin is equivalent to a rotation of 0 degrees and both are equivalent to the coordinate transformation ( 𝑥 , 𝑦 ) → ( 𝑥 , 𝑦 ) .

1. What is the rule for a 180 degree clockwise rotation?
2. What happens when you rotate 270 degrees clockwise?

What is the rule for a 180 degree clockwise rotation?

The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .

What happens when you rotate 270 degrees clockwise?

Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. Example: What will be the coordinate of a point having coordinates (3,-6) after rotations as 90° anti-clockwise and 270° clockwise? The coordinate of a point is (-6, -3).
