Chapter Overview
The chapter 'Parallel and Intersecting Lines' introduces students to the fundamental ideas of geometry. Students learn to identify parallel lines, intersecting lines, and angles formed by the intersection of lines. The chapter builds the foundation for understanding shapes, construction, and properties of geometrical figures.
