__ Parallel Postulate: __ If there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line.

The line that goes through point C is parallel to line AB.



Parallel postulate example--you can draw a line in any direction through point E, but only the__** red **__ line is parallel to line CD.

__ Perpendicular Postulate: __ If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line.



Angle 1 is perpendicular to angle 2.

__ Transitive Property of Parallel Lines: __ If two lines are parallel to the same line, then they are parallel to each other.



Line Q and line S are paralell to each other. Lizzie Luallin, Holly Fielder, Sara Meurer, Margie Stone

__ ﻿Parallel Postulate __

If there is a line and a point not on the line, then there is exactly one line through that point that is parallel to the given line.

If there is a line and a point not on the line, then there is exactly one line through that point that is perpendicular to the given line.
 * __ Perpendicular Postulate __**

If two lines are parallel to the same line, then they are parallel to each other.
