Answer
GH corresponds to GF
HK corresponds to FE
KG corresponds to EG
Work Step by Step
1. ∠HGK corresponds to ∠FGE
Those are vertical angles, therefore congruent.
2. ∠GHK corresponds to ∠GFE
∠GKH correspond to ∠GEF
Since HK and EF are parallel, angles are alternate interior angles, and congruent.
3. By matching the angles with lines you can figure out corresponding sides.
GH corresponds to GF
HK corresponds to FE
KG corresponds to EG
