"How do you determine the scale factor of a dilation?"

step 1) find the corresponding sides for each figure (that match up in a pair)
step 2) divide the new length by the old length to get your scale factor

example (see drawing)

|dw:1421291281232:dw|

new/old = 2/10 = 1/5

so the new square has dimensions that are 1/5th of the old square. The scale factor is 1/5. The fact that the scale factor is smaller than 1 means that the new figure is always smaller than the old.
