12.3 Transforming Shapes

You can use a combination of translations, reflections and rotations to transform a shape.

You can also describe the transformation that maps an object onto its image.

• To describe a reflection you must give: the equation of the mirror line.
• To describe a translation you must give: the column vector.
• To describe a rotation you must give: the centre of rotation (CP), the number of degrees of the rotation and the direction of the rotation.
