Answer 1

There is a similarity. Ill try my hardest to explain it. The ABC is exactly half of DEF.
Half of both the 8's is 4, and half of 6 is 3. One triangle bigger (GHI) would be 16 and 12. Thus they are all/both relevant to eachother. The transformation is each triangle is multiplied by 2 :)

Answer 2

Do you get it? :)
