1. Measure these lengths:

OA is 1.8 units

OA' is 0.9 units

2. Measure these lengths:

OB is 3 units

OB' is 0.9units

The scale factor of a dilation is the ratio of the corresponding side lengths of the original figure and the dilated figure. In this case, the original figure is line AB and the dilated figure is line A'B'.

Measure the lengths

OA: From the image, it appears that OA is marked as 1.8 units.

OB: Unfortunately, the image doesn't show the length of OB. However, we can infer it based on the scale factor. Since OA is 1.8 units and the scale factor is 2, OB would be double the length of OA, which is 1.8 units * 2 = 0.9 units.

OA': OA' is the image of OA after the dilation, and the scale factor is 2. Therefore, OA' would be 2 times the length of OA, which is 1.8 units * 2 = 0.9 units.
