If segment EF = 6 and segment FG = 3, which of the following statements are enough to prove that triangles EFI and GFH are similar?

Answer:
lines EI and HG are parallel
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem
If triangles EFI and GFH are similar
then
[tex]\frac{EF}{FG}=\frac{FI}{FH}=\frac{EI}{GH}[/tex]
substitute the given values
[tex]\frac{6}{3}=\frac{FI}{FH}=\frac{EI}{GH}[/tex]
[tex]2=\frac{FI}{FH}=\frac{EI}{GH}[/tex]
If lines EI and HG are parallel
then the triangles are similar by AA Similarity Theorem
therefore
lines EI and HG are parallel
