1. The problem states that triangles $\triangle GHI$ and $\triangle JKL$ are congruent, i.e., $\triangle GHI \cong \triangle JKL$.
2. By the definition of congruent triangles, corresponding angles and sides are congruent.
3. The order of vertices in the congruence statement tells us the correspondence: $G \leftrightarrow J$, $H \leftrightarrow K$, and $I \leftrightarrow L$.
4. Therefore, the valid congruences are:
- $\angle G \cong \angle J$
- $\angle H \cong \angle K$
- $\angle I \cong \angle L$
- $GH \cong JK$
- $HI \cong KL$
- $IG \cong LJ$
5. Note that $\angle H \cong \angle L$ is incorrect because $H$ corresponds to $K$, not $L$.
6. Similarly, $\angle I \cong \angle K$ is incorrect because $I$ corresponds to $L$, not $K$.
7. The side $IG$ corresponds to $LJ$ (or $JL$), which is the same segment as $LJ$.
Final answer: The valid congruences are $\angle G \cong \angle J$, $\angle H \cong \angle K$, $\angle I \cong \angle L$, $GH \cong JK$, $HI \cong KL$, and $IG \cong LJ$.
