Answer:

a) adjacent pairs: (1, 2), (1, 3), (2, 4), (3, 4)

b) linear pairs: (1, 3), (2, 4)

Explanation:

Adjacent angles share a vertex and an edge.

Adjacent pairs of marked angles in this diagram are ...

(1, 2), (1, 3), (2, 4), (3, 4)

__

Linear pairs of angles are adjacent angles whose non-shared sides form a straight line. The linear pairs of angles in this diagram are ...

(1, 3), (2, 4)

_____

Additional comment

The interior angles of a polygon are sometimes referred to a "adjacent" or "adjacent interior" when they share an edge. In that sense, angles 3 and 5 would be considered to be adjacent interior angles. (YMMV) This use of the term "adjacent angles" seems to be excluded from most dictionary definitions of adjacent angles.
