9.04b Enlargement Enlarge a simple shape from a given centre using a whole number scale factor, and identify the scale factor of an enlargement. Identify the centre and scale factor (including fractional scale factors) of an enlargement of a simple shape, and perform such an enlargement on a simple shape. Perform and recognise enlargements with negative scale factors. 9.04c Similar shapes Compare lengths, areas and volumes using ratio notation and scale factors.
