Learning objectives
Reflect a shape in a vertical or horizontal mirror line such as x = a or y = b, and at Extended in any line, such as y = x and y = −x
Rotate a shape through multiples of 90° about the origin, a vertex or the midpoint of an edge (about any centre at Extended), and translate a shape by a given column vector
Enlarge a shape from a given centre with a positive, fractional or, at Extended, negative scale factor
Describe a single transformation fully, giving every required detail such as the mirror line, the centre and angle, or the vector
Recognise that reflections, rotations and translations preserve congruence while enlargements produce similar shapes
