Are the two figures similar? D 6 15 9 c​
Viktor [21]

Answer:

These are similar. The scale factor is 1.5 going from ABC to DEF.

Step-by-step explanation:

What I did was divide the side lengths of DEF by the corresponding side on ABC.

12/8 = 1.5

9/6 = 1.5

15/10 = 1.5

Since the scale factor is the same on all three sides, these two figures are similar.
