About Geometry Worksheet Assignment 1.6:   

 

Assignment 1.6 is an introduction to parallel lines, parallel planes, and relationships of pairs of lines, pairs of planes and pairs of lines and planes.

 

Prerequisite Skill: Name lines (Assignments 1.1 and 1.3). 

 

Definitions:  Two lines that lie in the same plane and do not intersect are parallel lines,  

                           Two planes that do not intersect are parallel planes.  

                           A line and a plane that do not intersect are parallel.

                           Skew lines are lines that do not lie in the same plane.

 

Postulate:    Lines that lie in the same plane are either parallel or intersecting.
