If segment ef = 4 and segment fg = 2, which of the following statements are enough to prove that 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
segment fh over segment fi equals segment hg over segment ie equals two over four
points e, f, and g are collinear
∠f ≅ ∠f
