Given the information that triangle \( \triangle JKI \) is congruent to triangle \( \triangle TSU \), we can match the corresponding parts of the triangles. The congruence statement implies that:
- \( \angle K \cong \angle T \)
- \( \angle J \cong \angle U \)
- \( \angle I \cong \angle S \)
- \( JI \cong SU \)
- \( JK \cong TS \)
- \( KI \cong TU \)
To complete the statements based on the given information:
- \( JI \cong SU \)
Therefore, the complete statements are:
- \( \angle K \cong \angle T \)
- \( \angle U \cong \angle J \)
- \( JI \cong SU \)
