Question

Ryan transformed figure S into similar figure S′.

What scale factor did he use for the dilation?
A. 1/3
B. 1/2
C. 2
D. 3

Answer 1

D. 3

Explanation:

Rectangle S is ½ by 1½, so tripling each dimension would give you S':

½ x 3 = 1½

1½ x 3 = 4½

1½ x 4½ are your new dimensions, and are genuine dimensions!
