Step-by-step explanation
Step 1
vertical angles:
Vertical angles are pair angles formed when two lines intersect

so, we need to find a vertical angle in
a)
Figure 1:
blue angles are vertical, so

Figure 2:
hence, a pair of vertical angle is

Step 2
pair of adjacent angles:
Adjacent angles are two angles that have a common vertex and a common side but do not overlap

then
a)
for Figure 1
pair of adjacent angles

b) for Figure 2
pair of adjacent angles
