Answer:
C. SSS
Explanation:
We can see in the diagram that JM is congruent to JK.
Also marked congruent are ML and KL.
This gives us two sides.
The other piece that is definitely congruent is JL and JL. This is due to the reflexive property; any side is congruent to itself.
This gives us three sides of one triangle congruent to the corresponding three sides of another triangle; this is SSS.
