Transformations
Translation: move shape by a vector
Rotation: turn shape around a point (angle, direction, center)
Reflection: flip shape over a mirror line
Enlargement: scale shape using a center and scale factor (positive or negative)
Example
Example: Translate a shape 3 units right and 2 units down
Example: Rotate 90° clockwise about (0, 0)
Example: Reflect in the line \(y = x\)
Example: Enlarge by scale factor -2, center (1, 1)
