NCERT Class 9 Maths Exercise 11.1: Overview

Accurate drawings are done in this chapter. It characterises angles, lines, and shapes in geometry. To ensure correct shapes, candidates need a ruler and compass along with a protractor. Angle bisector and perpendicular bisector are the major constructions that are needed by Class 9 students.

However, before going to the solutions of Maths NCERT Class 9 Ex-11.1, let us have a brief overview of the Construction chapter from the NCERT book.

Class 9 NCERT Mathematics 11.1

NCERT Solutions for Constructions Exercise 11.1 Class 9 Maths deals with the introductory exercise of construction. In this exercise, some of the basic construction-related questions are asked about which candidates need to draw with their pencils and other construction items. Construction forms the core of geometry. In the early geometry chapters, candidates may learn the basic shapes of geometrical figures and more but how to draw them and how these structures are being drawn falls in this chapter.

For solving the questions present in NCERT Maths Class 9 Chapter 11, all the class 9 students need to have a geometry box which must contain the following items:

• A graduated scale: One side must not contain any markings of centimetres and millimetres, and on the other side inches and their parts must be marked off.
• A pair of dividers (or a divider) with all sorts of adjustments.
• A pair of compasses (or a compass) with the provision of fitting a pencil at one end
• A Protractor.
• A pair of a set – squares, one with angles 90°, 60° and 30° and the other with the following angles- 90°, 45° and 45°.

If you have got all of these in your hand, then let us go into the solutions of NCERT Maths chapter 11 class 9 through a step-by-step process.

About Exercise 11.1 Class 9 Maths

NCERT solutions for ex- 11.1 Class 9 Mathematics consists of construction problems. This chapter introduces students to all the basic questions of constructions and their corresponding problems. Construction is a very scoring part in Mathematics for class 9 students since the questions from this exercise are very easy if being practiced properly.

Questions asked in CBSE Class 9 Maths Ex 11.1 supervises the thinking ability of the students. Since the exercise deals with the construction introductory exercise, the basics of triangle-related questions as well as the angle-wise questions will also help to assess the concepts which will eventually get built-in amongst the students. 

Tips and Tricks To Solve Constructions

Geometric construction is known to be the process of drawing certain types of geometrical figures using two geometrical instruments, a compass, and a ruler (sometimes, a protractor is also used). Following are some of the tips and tricks which students of CBSE Class 9 must know in order to solve the Constructions problems:

Get advent with the theory: Firstly, all the students must know the basics of construction theories. For example, if the question asks to draw a line in cm, then students must know how to draw a straight line in geometrical and other mathematical measurements too.

Construction basics in geometry: For all Class 9 students, there are four basic construction procedures: Creation of a perpendicular bisector, creation of an angle bisector, construction of the parallel lines and creation of a perpendicular line through a given point. Every candidate must know these basics in order to solve a complicated question which they will find more in the subsequent Chapter 11 exercises.

Prevent parallax error: While drawing the construction shapes and structures, it is very important to prevent parallax error. Since this contributes to errors in taking readings. Every student must put their eyes on the object in close proximity to the scale of the measuring scale as possible. The eyes must be directly kept above the measuring scale.

Here is a solved example which can help:

In the above diagram, BF serves as the angular bisector for angle ABC. For this, scale and compass are needed for construction purposes. In similar ways, questions demanding to construct the angular and perpendicular bisector must also be drawn accordingly.

NOTE: Careful observation of each of the simplest markings is crucial for solving Construction numericals. All the candidates must focus carefully while solving the construction problems since a minute mistake while taking the readings of the marking can become a bigger issue if not solved properly.
