Statement                                    Reason$\angle 1 + \angle 8 = 180^o$   .......................

SOLUTION
Reason $:$
$\angle 1=\angle 5$   (Corresponding angles as $l||m$)
$\angle 5+ \angle 8={ 180 }^{ \circ }$   (Supplementary angles made on a line at a point)
Put $\angle 5 = \angle 1$
$\angle 1+\angle 8 ={ 180 }^{ \circ }$
