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
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
Yes, a pair of intersecting lines always forms a pair of vertical angles.
parallel
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.
you bet it can
which pairs of angles in the figure below are vertical angles
Because they are obtuse angles!
