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) |

Practice Questions for Transformations: Rotations
To fully describe a rotation, which three pieces of information are needed?
Shape A has vertices at (2, 1), (4, 1) and (4, 3). Shape B has vertices at (−1, 2), (−1, 4) and (−3, 4). Fully describe the single transformation that maps shape A onto shape B.
