Given triangle DEF similar to triangle GHF. Enter segments in the blanks provided that would result in a true equation.

Given:
The triangles DEF is similar to GHF.
The objective is to find a similar ratio of DF/DE.
Explanation:
Using the basic proportionality theorem, for the similar triangles DEF and GHF,
[tex]\frac{DE}{GH}=\frac{DF}{GF}=\frac{EF}{HF}\text{ . . . . .. .(1)}[/tex]Considering the first two ratios of equation (1),
[tex]\frac{DE}{GH}=\frac{DF}{GF}[/tex]On interchanging the segments further,
[tex]\frac{DF}{DE}=\frac{GF}{GH}[/tex]Hence, the required segment in the blanks is GF/GH.
