Question

In the diagram below line l is parallel to line m which angles are congruent to angle 1 ​

Answer 1

ANSWER

$\angle1 \cong \angle3$

$\angle1 \cong \angle8$

$\angle1 \cong \angle6$

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.
