Objectives
To identify relationships between figures in space
To identify angles formed by two lines and a transversal
In the Solve It, you used relationships among planes in space to write the instructions. In Chapter 1, you learned about intersecting lines and planes. In this lesson, you will explore relationships of nonintersecting lines and planes.
Essential Understanding Not all lines and not all planes intersect.
