A)

Given that the triangles △JKI and △TSU are congruent (△JKI ≅ △TSU), we can write the corresponding parts of the triangles as congruent. This is based on the congruence of triangles, which states that if two triangles are congruent, then their corresponding angles and sides are also congruent.

Based on the information provided, we complete the statements as follows:

1. <K ≅ <T
2. <U ≅ <S
3. ¯JI ≅ ¯SU
4. ¯JK ≅ ¯TU
5. <J ≅ <U
6. <I ≅ <S

These correspondences follow the order of the vertices in congruent triangles, ensuring that each angle and side corresponds correctly.
