Question

The polygons below are similar. Find the scale factor of the SMALLER figure to the LARGER.

A. 5:6

B. 3:5

C. 5:8

D. 2:5

Answer 1

A. 5:6

Explanation:

The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.

Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.

Therefore:

Scale factor = 25:30

Simplify

Scale factor of the smaller figure to the larger = 5:6
