That they are congruent.
They're supplementary
yes
Vertical Angles are a pair of nonadjacent anglesopposite each other formed when two lines cross.Vertical angles are two angles opposite of each other. Vertical angles will also always have equal angles.

They're supplementary
yes
true
True. Vertical angles are formed by the intersection of two lines and are always equal in measure, while complementary angles are two angles whose measures add up to 90 degrees. Since vertical angles can be any angle measure and are equal, they cannot be complementary unless both angles happen to be 45 degrees, which is not the case in general.
vertical angles
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
