Dilation 8/29/30 Objective: To dilate a figure using a scale factor less than and greater than 1.

What does it mean to Dilate something? When your pupils are dilated, it means that They change size. A Dilation is a transformation that changes The size , but not the shape, of a figure. A dilation can enlarge or reduce a figure What is a Scale Factor? A Scale Factor describes how much a figure Is enlarged or reduced. In math, we use the letter K for scale factor

Helpful Hint A scale factor between 0 and 1 reduces a figure A scale factor bigger than 1 enlarges it.

Try this: New coordinates of the image? Dilate the figure by a scale factor of 0.5. What are the New coordinates of the image?
