I need to find out if the triangles are congruent by SSS, SAS, or ASA. can someone show me how to do it

we know that
If two triangles are congruent, then its corresponding sides and its corresponding angles are congruent
In this problem
XW=YZ ------> is given
WA=ZA -----> is given
XA=YA -----> by Apply Pythagorean Theorem in a right triangle
and
is given
that means
two corresponding sides and the angle between the two sides are congruent
so
triangle XWA and triangle YZA are congruent by SAS
