9­6 DilationsObjective: To understand dilation images of figures

Dilation: A transformation that changes the size of the figure, but preserve angle measures

Notation: D(n,X)(Preimage) where n is the scale factor and x is the center of dilation

**Sometimes center of dilation will not be included

There are 2 types of dilations

Center of Dilation: The point that both the image and pre­image are projected from and will always connect corresponding parts.

(point of projection)

Scale Factor: How much the figure has dilated ­ found by multiplying
