Answer:
✅Vertical pair.
Step-by-step explanation:
When two straight lines intersect, they form pairs of two angles sharing the same vertex and are directly opposite each other. Thus, these angles are referred to as a vertical pair of angles.
In the diagram given, angle 5 and angle 8 are angles sharing the same vertex when two straight lines intersect. They are classified as vertical pair of angles. Angles of a vertical pair are congruent.
