NCERT Solutions for Class 9 Maths, Chapter 11 - Constructions

In earlier classes, you have learnt how to construct various geometrical figures such as angles, perpendicular bisectors, triangles, circles, and more. However, prior to this, you may not have understood the reasoning behind these constructions or may have never justified these constructions. In NCERT Solutions for Class 9, Maths, Chapter 11, you will not only learn how to construct certain geometrical figures but also know the reason behind such constructions. You will require a graduated scale, a compass, a pair of set squares, a pair of dividers and a protector for these constructions.

Let’s take a look at Class 9 Maths, Chapter 11 -Constructions

11.1 Introduction

11.2 Basic Constructions

11.3 Some Constructions of Triangles

11.4 Summary

In Class 9 Maths Chapter 10, you will learn – 

Section 11.2 – In this section, you’ll learn some basic geometrical constructions and reason behind these constructions. For instance, construction of the bisector of a given angle, construction of the perpendicular bisector of a given line segment, construction of the angle of 600 at the initial point of a given ray and more.

Section 11.3 – In this section, you will acquire the knowledge of some constructions of triangles in different situations. For instance, you will learn how to construct a triangle given its base, a base angle and sum of other two sides or construct a triangle given its base, a base angle and the difference of the other two sides and more.

All the concepts in this chapter are explained thoroughly with examples and their solutions for better understanding.  To know more about the NCERT Solutions for Class 9 Maths – Chapter 11 Constructions, you should explore the exercises below.  You can also download the NCERT Solutions for Class 9 Maths Chapter 11 PDF, solved by expert maths trainers.
