Lines and Angles

Introduction

In Chapter 5, you have studied that a minimum of two points are required to draw a line. You have also studied some axioms and, with the help of these axioms, you proved some other statements. In this chapter, you will study the properties of the angles formed when two lines intersect each other, and also the properties of the angles formed when a line intersects two or more parallel lines at distinct points.

You will learn about all types angles- acute angle, obtuse angle, straight angle, reflex angle, complete angle and also pairs of angles, Angle Sum Property of a Triangle.
