Step 1:Concept

If sides of one triangle are proportional to sides of another triangle, triangles are similar by SSS.

Step 2:Solution

\(\displaystyle{\frac{{{K}{L}}}{{{H}{F}}}}={\frac{{{14}}}{{{4}}}}={3.5}\)

\(\displaystyle{\frac{{{K}{G}}}{{{D}{F}}}}={\frac{{{24.5}}}{{{7}}}}={3.5}\)

\(\displaystyle{\frac{{{G}{L}}}{{{D}{H}}}}={\frac{{{21}}}{{{6}}}}={3.5}\)
