- shows a square enlarged with one of its vertices as the centre of enlargement
- enlarges a trapezium using a centre of enlargement that is external to the shape
- in discussion explains ‘the coordinates are doubled when you enlarge by a scale factor of two and (0, 0) is the centre for the enlargement, but that doesn't work if the centre is somewhere else on the grid‧

- enlarge shapes drawn in other quadrants, using (0, 0) as the centre of enlargement, and look at the effect on coordinates of vertices
- enlarge shapes using different centres of enlargement and scale factors
