ANSWER

$\angle1 \cong \angle3$

$\angle1 \cong \angle8$

$\angle1 \cong \angle6$

Step-by-step explanation

Since line l is parallel to line m,

$\angle1 \cong \angle3$

because the two angles are vertically opposite angles.

$\angle1 \cong \angle8$

because the two angles are corresponding angles.

$\angle1 \cong \angle6$

because the two angles are alternate exterior angles.
