The ___________ is the ratio that indicates how the side lengths of two similar polygons are related. For example, the map of a city may use one inch to represent one mile. The ____________ is the amount each side of a figure is multiplied by when the figure is proportionally enlarged or reduced in size. It is written as the ratio of a length in the new figure (image) to a length in the original figure.
