Assuming that the angles of JKL and NOM are in equal order, we know that congruent angles in a congruent triangle are equal to the corresponding angles in the other triangle. And assuming that JKL has the corresponding angles in the same order as NOM, statement D is correct.
This is because KL would be equal to OM not NM, JK is equal to NO not OM, JK and KL are apart of the same triangle, and LJ does equal MN assuming the corresponding angles are in the same order.
