The polygons in each pair are similar.
Find the scale factor of the smaller figure to the larger figure.
A) 8 : 9
B) 2 : 7
C) 1 : 2
D) 3 : 4

It's C) 1 : 2 (not asking, just informing)

C)1 : 2

Step-by-step explanation:

We want to find the scale factor of the smaller figure to the larger figure.

The scat factor is given by:

image length: corresponding object length

This time the smaller shape is the image and the bigger shape is the object:

The scale factor is :

6:12

Divide each term of the ratio by 6 to get:

1:2

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

i would say true? if the unit was informational and it "refreshed your understanding", then true.
