#9.01a
Reflect a simple shape in a given mirror line, and identify the mirror line from a shape and its image.
Identify a mirror line \(x = a\), \(y = b\) or \(y = ± x\) from a simple shape and its image under reflection.
#9.01b
Rotate a simple shape clockwise or anti-clockwise through a multiple of 90° about a given centre of rotation.
Identify the centre, angle and sense of a rotation from a simple shape and its image under rotation.
#9.01c
Use a column vector to describe a translation of a simple shape, and perform a specified translation.
#9.01d
Perform a sequence of isometric transformations (reflections, rotations or translations), on a simple shape. Describe the resulting transformation and the changes and invariance achieved.
