Actually, It is this.
Question: Angle 1 and 4 are called ___ angles?
Answer: Supplementary
Yes, a pair of intersecting lines always forms a pair of vertical angles.
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
Two vertical angles cannot be a linear pair because vertical angles are formed by the intersection of two lines and are opposite each other, while a linear pair consists of two adjacent angles that sum to 180 degrees and share a common side. Since vertical angles are equal in measure, they are not adjacent and do not share a side, thus they cannot form a linear pair. Therefore, it is impossible for vertical angles to be a linear pair.
you bet it can
Vertical angles occur when 2 angles are directly across from each other and are congruent.
No
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
No

No, in fact, vertical angles can't be a linear pair. Vertical angles are opposite from each other which also make them equal each other. A linear pair has two angles adjacent to each other that eqaul 180 degrees.

which pairs of angles in the figure below are vertical angles
Vertical angles occur when 2 angles are directly across from each other and are congruent.
Because they are obtuse angles!
