The sixth chapter of NCERT Class 9 Maths deals with Lines and Angles. This topic introduces you to the basic Geometry primarily focusing on the properties of the angles formed
i) when two lines intersect each other and
ii) when a line intersects two or more parallel lines at distinct points.
Now, you all must be wondering why we are studying Lines and Angles. What are the real-life applications of it? The answer is that lines and angles are everywhere around us. The architecture uses lines and angles to design the structure of a building. When you stop at a signal and then move on when the signal light is green, then you either take a left angle turn or right angle turn or move in a straight line. When you have to find the height of a tower or location of an aircraft, then you need to know angles. In NCERT Class 9 Maths Chapter 6, you will learn all the concepts of Lines and Angles.
