Final answer:
The scale factor that takes quadrilateral Q to quadrilateral R is 1/4.
Step-by-step explanation:
The scale factor that takes quadrilateral Q to quadrilateral R is 1/4.
A scale factor represents the ratio of corresponding side lengths in similar figures. In this case, since quadrilateral R is a scaled copy of quadrilateral Q, we can say that the corresponding side lengths of the two quadrilaterals are in a 1:4 ratio.
For example, if a side length of quadrilateral Q is 8 units, the corresponding side length of quadrilateral R would be 8 units multiplied by the scale factor, which is 1/4. Therefore, the side length of quadrilateral R would be 2 units.
