Which of the following statements is true only if triangles EFI and GFH are similar?

Line segments EG and HI intersect at point F, forming triangles EFI and HFG Line a intersects with both triangles at point F.

two segment FI equals three segment FH
Lines EI and HG are parallel
Points E, F, and G are collinear
segment EI over segment FI = segment GH over segment FH

Two segment FI equals three segment FH
