For a dilation, if the scale factor n is greater than 1 then the resulting image is a(n)

• enlargement

• scale factor

• dilation

A dilation image cannot have any points in common with its pre-image

• True

• False

To find the scale factor of a dilation you should

• Use the ratio of corresponding sides with the image as the numerator and the pre-image as the denominator

• Use the ratio of corresponding sides with the pre-image as the numerator and the image as the denominator

• Count the sides of the figure

• Find the Area of the figure
