Question
In the given figure, decide whether $l$ is parallel to $m.$
✓
Answer
In the above figure, there is a pair of angles $126^{\circ}$ and $44^{\circ}$ which are on the same side of the transversal $n$.
Sum of these two interior angles on the same side of the transversal $=126^{\circ}+44^{\circ}=170^{\circ}$
Clearly, their sum is not equal to $180^{\circ}$. So, the angles are not supplementary.
Therefore,
The lines I and m are not parallel to each other.
