Question

What is the scale factor from ABC to DEF?

Answer 1

0 so D

Explanation:

The shape didnt change at all. All the sides are 5 for both triangles.

Answer 2

C
Explanation: any side you have is multiplied by some sort of scale factor. In this instance, if you multiply the sides of ABC by a scale factor of 1, you will get the similar side lengths of DEF (the same as ABC)
Answer D may be tempting but multiplying your sides by 0 would make the triangle…well disappear :D
