# Linear Pair Theorem

Theorem of linear pairWhen two angles form a linear pair, they are complementary. The theorem ("The linear pair theorem"): When the angles pBAD and pDAC form a linear pair, then they are complementary. Posted: ?PAS and ?SAL are a linear pair.

## Geometric sets

Correspondingly, when two co-planar axes are intersected by a transverse so that two corresponding angle have the same dimension, they are mutually paralleled. Reverse of Postulate Multiple Line.

postulate multiple line postulations: Corresponding angels have the same dimension if two straight line are running and are intersected by a cross line. There are two additional brackets to the same bracket that are matched to each other: Follows the vertical angular theorem; the evidence is the same as that of the vertical angular theorem.

Squareness theorem evidence: (Evidence: given at any right angle
