Procedures

Triangle ABC ~ triangle DEF. Triangle ABC has sides AB = 2, BC =
5, AC = 4. Triangle DEF has sides DE = 6, EF = 15, DF = 12. What
is the scale factor from ABC to DEF?

3 (using matched corresponding sides, e.g. DE/AB = 6/2 = 3)

2.5 (comparing AC = 4 in ABC to EF = 15 in DEF, not the corresponding side)

It cannot be determined because the triangles have different side lengths

1, because both are triangles
