Answer:
lines r and s
Step-by-step explanation:
we know that
Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
When the lines are parallel, the alternate interior angles are equal
so
In this problem
If lines r and s are parallel
then
m∠4=m∠5 ----> by alternate interior angles
