vertical angles theorem
The linear pair conjecture states that if two angles form a linear pair, the sum of the angles is 180 degrees.
No
parallel
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
you bet it can
no it's impossible
Yes, they can.
sometime true
No. All linear pair angles are supplementary, but supplementary angles do not have to be a linear pair.

Yes.
All supplementary angles do not form a linear pair. The opposite angles of any quadrilateral inscribed in a circle (a cyclic quadrilateral) are supplementary but they are not a linear pair. However, all linear pair are supplementary.
No, angles that form a linear pair are supplementary.
No
