Answer/Explanation:
Segment AB is acting like a transversal line that cuts across the two straight lines, line m and line l.
If two corresponding angles formed are congruent to each other, thus, the two parallel lines intercepted by a transversal is said to be parallel.
Therefore, the reasons that Elena would provide to support her statement that line m is parallel to line l is:
Angle A is congruent to Angle D.
They are corresponding angles. Corresponding angles are equal. This makes line m parallel to line l.
