# Interactive video lesson plan for: Construction: Basic Dilation from an external point

#### Activity overview:

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). If you enjoy this video please like, subscribe and comment.
