Answer:
- They are adjacent angles
- They are a linear pair
- They are supplementary angles
- Their sum is [tex]180^{\circ}$[/tex]
Step-by-step explanation:
Since [tex]\angle 1[/tex] and [tex]\angle 4[/tex] are on one side of a line, their sum is [tex]180^{\circ}[/tex], meaning they are supplementary. This also defines them as a linear pair and both angles are adjacent to one another. None of the other answer choices are implied in the figure, thus:
- They are adjacent angles
- They are a linear pair
- They are supplementary angles
- Their sum is [tex]180^{\circ}$[/tex]
