Name two pairs of congruent angles

∠JKL and ∠GKH

Step-by-step explanation:

1. Because these intersecting lines are forming opposite pairs of angles, there  are some vertical angles. Vertical angles are congruent.

2. As you can see, ∠JKL is 55°. The angle that forms the pair of opposite angles with ∠JKL is ∠GKH.

3. As aforementioned, because these two angles are vertical angles, they're congruent.

Therefore, two pairs of congruent angles are ∠JKL and ∠GKH.
