# NCERT Solutions Class 9 Maths Chapter 6 Lines and Angles

Lines and angles are the basic geometric elements significantly important in mathematics as well as in real life. They are the basic building blocks of geometry required to understand many advanced concepts. NCERT solutions for class 9 maths chapter 6 Lines and Angles focus on studying the relationship between lines and angles. It involves learning the properties of the angles formed by two intersecting lines and the properties of the angles formed by a line intersecting two or more parallel lines. By solving exercises in this chapter 6 of ncert class 9 maths, students will learn about the properties of the sums of angles formed by these types of lines and more.

A line with a start and endpoint is known as a line segment and a line with one endpoint is known as a ray. Two rays originating from the same endpoint form an angle where rays are called the arms of the angles and the endpoint is known as the vertex of the angle. Gaining a deep understanding of lines and angles is vital for both academics and real life.
