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,

Considering the first two ratios of equation (1),

On interchanging the segments further,

Hence, the required segment in the blanks is GF/GH.
Combine multiplied terms into a single fraction
Multiply the numbers
Subtract 7 from both sides of the equation
Simplify
Multiply all terms by the same value to eliminate fraction denominators
Shape D is not a quadrilateral
I'm pretty there's a complement
suck it
