Answer

The sum of the three angles in any triangle is $180^{\circ}$ Therefore: $\angle K \cong \angle L$

Work Step by Step

The sum of the three angles in any triangle is $180^{\circ}$ $180 = m\angle K+m\angle JHK+m\angle HJK = m\angle L+m\angle JHL+m\angle HJL$ $m\angle K = m\angle L$ $\angle K \cong \angle L$
