1. Where the angles in a linear pair are supplementry, and if parallel lines are cut by a transversal, then the interior angles are congruent, and if two lines are cut by a transversal so that a pair of alternate interior angles are congruent, then the two lines are parallel. That's what makes up a linear pair postulate anyway.
2. If two adjacent angle's unshared sides form a straight angle, then they are a linear pair.
3.If two angles form a linear pair,then they are supplementary.

What is Supplement Postulate?
The Supplement Postulate states that if two angles form a linear pair, then they are supplementary.
What is the Linear pair theorem?
Actually, it's the Linear Pair Postulate, which is... If two angles form a linear pair, then they are supplementary; that is, the sum of their measures is 180 degrees.
which of the following reasons can be used for statement 2 of the proof?
vertical angles theorem
What is the Linear Pair conjecture?
The linear pair conjecture states that if two angles form a linear pair, the sum of the angles is 180 degrees.
Can a pair of obtuse angle form linear pair?
no
