Polygon D has been dilated to create polygon D′.
Polygon D with top and bottom sides labeled 8 and left and right sides labeled 9.5. Polygon D prime with top and bottom sides labeled 6.4 and left and right sides labeled 7.6.
Determine the scale factor used to create the image.
Scale factor of 0.6
Scale factor of 0.8
Scale factor of 1.2
Scale factor of 1.6
Scale factor of 0.8
To find the scale factor, you divide the corresponding sides of the original polygon and the dilated polygon. In this case, 6.4/8 = 0.8 and 7.6/9.5 = 0.8. Therefore, the scale factor used to create the image is 0.8.
