Linear Pair Theorem Definition

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.

Parallel Line Postulation: 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
