### Enlargements

Enlargements make shapes bigger or smaller than, but still proportional to, their original shapes.

Shapes can be enlarged by a particular **scale factor**. This ensures that the enlarged shape is bigger (or smaller) but proportional to the original shape.

A scale factor is the proportion by which the size of the shape is increased. If the shape was was enlarged by a scale factor of 3, it would be 3 times the size of the original shape.

The centre of enlargement controls the **position** of an enlarged shape relative to the original shape.

We can put these concepts together to enlarge a shape by a given scale factor from a particular centre of enlargement.
