Explanation:
To find the scale factor, we need to look at the proportions of each figure and compare them to each other.

For example, we can look at the distance between point A and point C and compare it to the distance between point A’ and point C’ (on the second figure).

On the first figure, the distance is 2 units and on the second figure, the distance is 6 units. To get from 2 to 6 we would need to multiply 3, so therefore, the scale factor is 3.
