OpenStudy (mathstudent55):
good
Now does the information you have seem to fit into any of those?
The information you know is:
Two right triangles.
The hypotenuses are congruent.
The leg of one triangle is congruent to the corresponding leg of the other triangle.

BTW, there is no ssa, but there is sss.
