Study Notes
Rotation Transformation Rules
- 90° counterclockwise rotation: (x, y) transforms to (-y, x).
- 180° rotation: (x, y) transforms to (-x, -y).
- 270° rotation: (x, y) transforms to (y, -x).
- 360° rotation: (x, y) remains as (x, y).
Reflection Transformation Rules
- Reflection across the line y = x: (x, y) transforms to (y, x).
- Reflection across the line y = -x: (x, y) transforms to (-y, -x).
Translation Transformation Rules
- Translation a units to the right: (x, y) changes to (x + a, y).
- Translation a units to the left: (x, y) changes to (x - a, y).
- Translation b units up: (x, y) changes to (x, y + b).
- Translation b units down: (x, y) changes to (x, y - b).
