What is the linear pair postulate?
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.
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees. linear pair means that the angles which form on the same line and add up to 180.
