Answer:

  2.  j, k

  3.  s, r

Step-by-step explanation:

In each figure, the shared side of the angles of interest is the transversal. The lines it crosses are the parallel lines.

2.  ∠1 and ∠2 are same-side interior angles with respect to transversal h and parallel lines j and k.

3. ∠9 and ∠10 are alternate exterior angles with respect to transversal j and parallel lines s and r.
