Answer: AAS
=================================================
Step-by-step explanation:
We have two pairs of angles that are congruent
- angle JML = angle LKJ (both right angles or 90 degree angles)
- angle JLM = angle LJK (shown with tickmarks)
So that takes care of the two "A"s in "AAS".
The "S" refers to JL = JL being the pair of congruent sides. The sides perfectly overlap and we use the reflexive property here. The reflexive property says that any segment is congruent to itself.
Keep in mind we aren't using ASA because the congruent sides are not between the congruent angles.
