A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image. The image always has a prime after the letter such as A' . resource: http://www.mathwarehouse.com/transformations/dilations/dilations-in-math.php

One example is photographic enlargements.
Dilations are a geometric transformation that results in the image being similar to the preimage.
