Rotation Formulas about Origin
| Rotation | Formula | Example |
|---|---|---|
| 90° clockwise | (x, y) → (y, -x) | (3, 1) → (1, -3) |
| 90° anticlockwise | (x, y) → (-y, x) | (3, 1) → (-1, 3) |
| 180° (both) | (x, y) → (-x, -y) | (3, 1) → (-3, -1) |
| 270° clockwise | Same as 90° ACW | (3, 1) → (-1, 3) |
