A dilated figure changes it's shapes size.When you zoom in on a photo you are making things bigger .zooming relates to dilation by making some thing bigger because in dilation you make something bigger or smaller . If a figure undergoes a dilation with a scale factor of 1.5 the figure does get bigger because the scale factor is greater than one.It is not the same if the scale factor is 0.5 because o.5 is less than 1 and if a scale factor is less than one the the dilation's will be smaller. A dilation differs from a translation because in a translation you change the location and in a dilation you change the size.
