The scale factor is a positive number that tells you how much to enlarge or shrink the point. If the scale factor is greater than 1, the point moves away from the origin.

Multiplication of coordinates by a scale factor given the origin as the center. Two figures are similar if they are the same shape but not necessarily the same size. One way to create similar figures is by dilating. A dilation makes a figure larger or smaller such that the new image has the same shape as the original. Dilation: An enlargement or reduction of a figure that preserves shape but not size.

Examples, videos, and solutions to help Grade 8 students learn how to describe the effect of dilations on two-dimensional figures using coordinates. Worksheets for Grade 8. Dilation has a multiplicative effect on the coordinates of a point in the plane. Classwork Example 1 Students learn the multiplicative effect of scale factor on a point. Note that this effect holds when the center of dilation is the origin. In this lesson, the center of dilation will always be assumed to be 0, 0. Example 3 The coordinates in other quadrants of the graph are affected in the same manner as we have just seen.
