Answer:
The triangles are congruent as per AAS congruence.
Explanation:
AAS congruence states that when two triangles are congruent when their two angles are equal and the side not contained between those angles is also equal.
Let us have a look at the given triangles
and

It is given that they are right angled triangles and following dimensions are also equal:
1.

2.

3. The side not between the angles i.e. the hypotenuse SU = LM
So, the two triangles
and
are congruent as per AAS congruence.
i.e.
as per AAS congruence.
