Answer:
(D) NI≅AC
Step-by-step explanation:
From the given information, it is given that in ΔINF and ΔCAT, CA=FN and ∠CAT=∠FIN.
Therefore, from ΔINF and ΔCAT
∠ACT=∠NIF (given)
CA=NI (given)
∠CAT=∠INF
thus, by ASa rule of congruency,
ΔINF ≅ ΔCAT
Hence, CA=NI is the additional information which can be needed to prove the triangles are congruent.
Hence, option D is correct.
