About Geometry Worksheet Assignment 1.5:       

 

Assignment 1.5 is an introduction to intersecting planes, and intersecting lines and planes.

 

Prerequisite Skills: Name points, lines, and planes (Assignment 1.4). 

 

Definition:  Planes that have common points are intersecting planes.

 

Postulates:  The intersection of two planes is a line.

                           If a line intersects a plane and does not lie in the plane, the intersection is a point.
