NCERT Solutions for Class 9 Maths Chapter 6 Lines And Angles

 

NCERT Solutions for Class 9 Maths Chapter 6 Lines And Angles-

In the previous chapter, we have studied that to draw a line we required a minimum of two points. In this chapter, we will study the properties of angles formed when a line intersects two or more than two parallel lines at different points and the angles formed when the two lines intersect each other. This chapter contains 3 exercises with 18 questions in them. The NCERT Solutions for Class 9 Maths Chapter 6 Lines And Angles are solved by our subject experts to help students in the preparation of class 9 CBSE final examination as well as in various competitive exams like NTSE, Indian National Olympiad (INO), etc. These NCERT solutions are the detailed explanation and solution of class 9 Maths NCERT textbook.

In NCERT Class 9 Maths Chapter Lines And Angles, we will learn the concepts related to lines and angles.  Lines and angles are everywhere around us. To design the structure of the building an architecture uses both lines and angles. When we have to find the height of a building or a tower, then we need to know angles. In this chapter, we will learn concepts of vertically opposite angles, supplementary angles, and complementary angles and also study properties of parallel lines and transversal lines, intersecting lines, non-intersecting Lines and angle sum property of the triangle.

Some basic terms and their figures that we are going to discuss in NCERT Class 9 Maths Chapter Lines And Angles are-
