👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

This video explains how artists can enlarge or reduce drawings using scale factors. It covers the concept of scale factors and demonstrates how to calculate them for both enlargements and reductions.

When you change the size of a shape by making it larger or smaller, the degree to which you change its size is measured by something called its scale factor. A linear scale factor is simply the size of the enlargement or reduction of a...
