Answer:
IJ , scale factor = 3
Step-by-step explanation:
Considering the positions of the two figures, it can be seen that
IJ is the corresponding side to RQ
The scale factor is the ratio of corresponding sides image to original.
IJ and RQ are corresponding sides
From the diagram
IJ = 3 units and RQ = 1 unit , then
scale factor = [tex]\frac{IJ}{RQ}[/tex] = [tex]\frac{3}{1}[/tex] = 3
