Answer
A) Yes
B) ASA
Work Step by Step
A) Since it is a right triangle, we can use a leg and an angle to prove congruence. Since they are both right triangles with corresponding legs and angles congruent, it is true that leg angle can be used to show congruence.
B) We see the legs are congruent and that the two angles on either side of the legs are congruent. Thus, the triangles are congruent by ASA.
