Answer:
line a
Step-by-step explanation:
Corresponding angles both have a vertex that is a point on the transversal. The transversal is one side of each of the corresponding angles. Here, the vertices of angles 2 and 6 are the intersection of lines (n, a) and (m, a). The line these have in common is line a.
The transversal is line a.
