D. [tex]$\angle 4$[/tex] and [tex]$\angle 5, \angle 2$[/tex] and [tex]$\angle 16$[/tex]



Answer :

To determine which choice includes two pairs of adjacent angles from the coordinate plane, consider the geometric definition of adjacent angles. Adjacent angles share a common side and a common vertex, but they do not overlap.

Let's analyze each choice:

1. [tex]$\angle 1$[/tex] and [tex]$\angle 4, \angle 2$[/tex] and [tex]$\angle 5$[/tex]

To verify if these are pairs of adjacent angles:
- [tex]$\angle 1$[/tex] and [tex]$\angle 4$[/tex]: These angles must share a common side and vertex.
- [tex]$\angle 2$[/tex] and [tex]$\angle 5$[/tex]: These angles must share a common side and vertex.

2. [tex]$\angle 6$[/tex] and [tex]$\angle 5, \angle 3$[/tex] and [tex]$\angle 2$[/tex]

To verify if these are pairs of adjacent angles:
- [tex]$\angle 6$[/tex] and [tex]$\angle 5$[/tex]: These angles must share a common side and vertex.
- [tex]$\angle 3$[/tex] and [tex]$\angle 2$[/tex]: These angles must share a common side and vertex.

3. [tex]$\angle 6$[/tex] and [tex]$\angle 4, \angle 11$[/tex] and [tex]$\angle 4$[/tex]

To verify if these are pairs of adjacent angles:
- [tex]$\angle 6$[/tex] and [tex]$\angle 4$[/tex]: These angles must share a common side and vertex.
- [tex]$\angle 11$[/tex] and [tex]$\angle 4$[/tex]: These angles must share a common side and vertex.

4. [tex]$\angle 4$[/tex] and [tex]$\angle 5, \angle 2$[/tex] and [tex]$\angle 16$[/tex]

To verify if these are pairs of adjacent angles:
- [tex]$\angle 4$[/tex] and [tex]$\angle 5$[/tex]: These angles must share a common side and vertex.
- [tex]$\angle 2$[/tex] and [tex]$\angle 16$[/tex]: These angles must share a common side and vertex.

The choice [tex]$\angle 1$[/tex] and [tex]$\angle 4, \angle 2$[/tex] and [tex]$\angle 5$[/tex] includes two pairs of adjacent angles.
