In this video I take you through the construction of two dilations in the plane. The first, a dilation by 2, and the second, a dilation by 1/4. You will need a compass and straightedge to follow along. These are both basic dilations- look for my next video to learn a more sophisticated technique that will work for any scale factor (such as 2/3 or 8/5, etc).
