Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and is the longest side of DEF. Triangle ABC is a scaled copy of triangle DEF with what scale factor?

scale factor = 1.5

Step-by-step explanation:

Given: Triangle ABC is a scaled copy of triangle DEF.

Side AB = 12 cm and is the longest side of ABC.

Side DE = 8 cm and is the longest side of DEF.

AB is corresponds DE (longest side of both triangles)

So,

Hence, the scale factor = 1.5.
