Explanation:
Given that triangle TAM is congruent to the triangle HAM.
We know that corresponding sides of congruent triangles are equal so we can write:
TA = HA
AM = AM
TM = HM
comparing these with given choices we see that, (AM = AM) is the only matching answer.
Hence final answers is the first choice
