The correct answer is:
They are corresponding angles
.
Explanation:
The two parallel runways are cut by the taxiway. This taxiway serves as a transversal.
When two parallel lines are cut by a transversal, corresponding angles are angles that are on the same side of the transversal and in the same relative position compared to the parallel lines.
∠1 and ∠5 are both above the taxiway (transversal). They are also both to the right of their corresponding parallel lines. This makes them corresponding angles.
