## Overview of the topics of Class 9 Chapter 6 Solutions Lines and Angles

In the previous chapter of Introduction of Euclidean Geometry students were introduced to some of the concepts that you will be dealing with now. Chapter 6 consists of the properties of lines and angles in relation to each other. Some key points include:

- Three or more points on a line are collinear, otherwise, they are non-collinear
- Angles are measured between two rays originating from the same point
- Complementary angles add up to 90 and supplementary add up to 180.

## The axioms in NCERT chapter 6 class 9 explained?

**Axiom 1:**The sum of adjacent angles formed by a ray on a line is 180^{o}**Axiom 2:**if the sum of two adjacent angles is 180°, then the non-common arms of the angles form a line.

These two axioms together form the Linear Pair Axiom.

## FAQs (Frequently Asked Questions):
