The scale factor of the dilation is 0.5

<h3>How to determine the scale of dilation?</h3>

From the figure, we have the following lengths:

AB = 2

AB' = 1

The scale factor of dilation is then calculated as:

Scale factor = AB'/AB

This gives

Scale factor = 1/2

Evaluate

Scale factor = 0.5

Hence, the scale factor of the dilation is 0.5
