Answer:
C. TA
Explanation:
I'm guessing you mean ΔMAN ≅ ΔTAP and not ΔATAP.
Because these two triangles are congruent (a.k.a equal), the corresponding segments are equal.
Literally means that the first and last points of the first triangle make up a line that is equal to the line that you find from doing the same thing to the other triangle and so on.
This gives us MA = TA, AN = AP, MN = TP.
