Triangles TAM and HAM have common side AM.
Also,∠TAM =∠HAM and ∠TMA=∠HMA.
We have 2 angles of one triangle, that are congruent 2 angles of the second triangle, and we have the common side that are included for these angles.
So,
we need theorem ASA.
AM is congruent to MA
HAM is congruent to TAM
Its angle side angle
