In previous courses, you have studied different types of similar figures. In a previous resource, you examined similarity relationships using scale factor and proportion.
In this resource, you will investigate dilations, which are enlargements and reductions of given figures.
An enlargement is a type of dilation that results in a larger figure. Enlargements are used in photography to print a larger picture from a particular image. Enlargements are also used in architecture where a pattern in a small part of a building is taken in a larger part of the building.
A reduction is a type of dilation that results in a smaller figure. A camera works by creating an image of a real-life scene that is proportionally smaller. This image is called a reduction. Video game designers may also use reductions in order to create sharper and better graphics.
