Dilation

=
Dilation is a similarity in which a figure is enlarged or reduced using a scale factor does not equal 0 without altering the center. =====

A dilation is where the polygon grow or shinks, but it keeps the same overall shape, like zooming in and out on a camera. The pictures below are an example. In this picture, the red rectangle ABCD is larger, and look to the right, the red rectangle ABCD is smaller, but the same shape.



When you dilate a figure you create similar figures. When you dilate you need a scale factor, so for example, n is the scale factor. if n>1= larger image, and if n<1= smaller image. You also need to know the center of dilation.

A dilation is a transformation that produces an image that is the same shape as the original, but a different size.

Steps: 1. Draw image 2. Multiply the size by the dilation 3. Draw image for the new size
