If \( \triangle JKL \cong \triangle NOP \), we can conclude that all corresponding parts of the triangles are congruent. This is a result of the definition of triangle congruence.
Based on the congruence of the triangles, the following conclusions can be drawn:
- Conclusion #1: \( \angle J \cong \angle O \) (corresponding angles)
- Conclusion #2: \( \angle L \cong \angle P \) (corresponding angles)
- Conclusion #3: \( LJ \cong PO \) (corresponding sides)
- Conclusion #4: \( JK \cong OP \) (corresponding sides)
In summary, all the conclusions you listed are correct given that \( \triangle JKL \cong \triangle NOP \). Each corresponding angle and side is congruent.
