Given:

• AB = 18

,

• AC = 24

,

• BC = 21

,

• EF = 7

Let's find the scale factor of triangle ABC to DEF.

To find the scale factor of similar figures, divide a side in the transformed figure by the length of the corresponding side in the original figure.

Thus, we have:

$\text{ scale factor = }(EF)/(BC)=(7)/(21)=(1)/(3)$

Therefore, the scale factor of ABC to DEF is 1/3.

ANSWER:

C. ¹/₃
