A dilatation is a transformation that changes the size of a polygon, but not its shape.
In order to perform a dilatation on a polygon, you need to know
Recall our previous example, which had centre \(O\) and a scale factor of \(3\).
Draw the image of the square \(JKLM\) under a dilatation using the centre of the square and a scale factor of \(\dfrac{1}{3}\).
Solution
Draw the image of the parallelogram \(ABCD\) under a dilatation using the centre of the parallelogram and a scale factor of \(4\).
