the polygons in each pair are similar. find the scale factor of the smaller figure to the larger figure.​

smaller figure/larger figure = 3/12 = ¼

Step-by-step explanation:

Scale factor = Smaller figure side length / corresponding side length of the larger figure.

Length of a side of the smaller figure = 3

Corresponding Length of a side of the larger figure = 12

Scale factor = smaller figure/larger figure = 3/12 = 1/4
