Answer:
Lines r and s are parallel.
Step-by-step explanation:
When a line intersects two parallel lines, the opposite or corresponding angles formed are said to be equal.
Here, we are given that m∠4 = m∠5 which are the opposite angles when line l intersects the two lines a and b.
For this given condition to be true, lines r and s have to be parallel for which ∠1 = ∠5, ∠2 = ∠6, ∠3 = ∠6, ∠4 = ∠5 (and so forth), all are equal.
Therefore, we can conclude that lines r and s are parallel.
