The answer is choice A. AA
AA = angle angle
The AA similarity theorem is where you look for 2 pairs of congruent angles of two triangles. If you are able to find 2 pairs of those angles, then you've proven the triangles to be similar. In this case, we have a pair of 44 degree angles (angle K, angle Q) and we also have a pair of 90 degree angles because they are right triangles. So this is enough to prove that triangle PQR is similar to triangle JKL
