Significance of Mathematics in Class 9

Mathematics is an important subject for students of all ages. It helps students to develop problem-solving and critical-thinking skills, and to think logically and creatively. In addition, mathematics is essential for understanding and using many other subjects, such as science, engineering, and finance.

CBSE Class 9 is an important year for students, as it is the foundation year for the Class 10 board exams. In Class 9, students learn many important concepts in mathematics that will help them to succeed in their board exams and in their future studies. Therefore, it is essential for students to understand and master the concepts taught in Class 9 Mathematics .

Case studies in Class 9 Mathematics

A case study in mathematics is a detailed analysis of a particular mathematical problem or situation. Case studies are often used to examine the relationship between theory and practice, and to explore the connections between different areas of mathematics. Often, a case study will focus on a single problem or situation and will use a variety of methods to examine it. These methods may include algebraic, geometric, and/or statistical analysis.

Example of Case study questions in Class 9 Mathematics

The Central Board of Secondary Education (CBSE) has included case study questions in the Class 9 Mathematics paper. This means that Class 9 Mathematics students will have to solve questions based on real-life scenarios. This is a departure from the usual theoretical questions that are asked in Class 9 Mathematics exams.

The following are some examples of case study questions from Class 9 Mathematics:

Class 9 Mathematics Case study question 1

There is a square park ABCD in the middle of Saket colony in Delhi. Four children Deepak, Ashok, Arjun and Deepa went to play with their balls. The colour of the ball of Ashok, Deepak,  Arjun and Deepa are red, blue, yellow and green respectively. All four children roll their ball from centre point O in the direction of   XOY, X’OY, X’OY’ and XOY’ . Their balls stopped as shown in the above image.

Answer the following questions:

Answer Key:

Class 9 Mathematics Case study question 2

• Now he told Raju to draw another line CD as in the figure
• The teacher told Ajay to mark  ∠ AOD  as 2z
• Suraj was told to mark  ∠ AOC as 4y
• Clive Made and angle  ∠ COE = 60°
• Peter marked  ∠ BOE and  ∠ BOD as y and x respectively

Now answer the following questions:

• 2y + z = 90°
• 2y + z = 180°
• 4y + 2z = 120°
• (a) 2y + z = 90°

Class 9 Mathematics Case study question 3

• (a) 31.6 m²
• (c) 513.3 m³
• (b) 422.4 m²

Class 9 Mathematics Case study question 4

How to Answer Class 9 Mathematics Case study questions

To crack case study questions, Class 9 Mathematics students need to apply their mathematical knowledge to real-life situations. They should first read the question carefully and identify the key information. They should then identify the relevant mathematical concepts that can be applied to solve the question. Once they have done this, they can start solving the Class 9 Mathematics case study question.

Students need to be careful while solving the Class 9 Mathematics case study questions. They should not make any assumptions and should always check their answers. If they are stuck on a question, they should take a break and come back to it later. With some practice, the Class 9 Mathematics students will be able to crack case study questions with ease.

Class 9 Mathematics Curriculum at Glance

At the secondary level, the curriculum focuses on improving students’ ability to use Mathematics to solve real-world problems and to study the subject as a separate discipline. Students are expected to learn how to solve issues using algebraic approaches and how to apply their understanding of simple trigonometry to height and distance problems. Experimenting with numbers and geometric forms, making hypotheses, and validating them with more observations are all part of Math learning at this level.

The suggested curriculum covers number systems, algebra, geometry, trigonometry, mensuration, statistics, graphing, and coordinate geometry, among other topics. Math should be taught through activities that include the use of concrete materials, models, patterns, charts, photographs, posters, and other visual aids.

Direction: BSE stands for a disease called Bovine Spongiform Encephalopathy. “Bovine” means that the disease affects cows, “spongiform” refers to the way the brain from a sick cow looks spongy under a microscope, and “encephalopathy” indicates that it is a disease of the brain. This disease is commonly called “mad cow disease.” A farmer has a field ABCD formed by two pair of parallel roads as shown below in which l ||m and p || q. His four cows suffering from BSE. Thus, he tied them at four corners of the field ABCD. Q. If cow at C and cow at D is 2 km apart, then what is the distance between cow at A and cow at B?

So, AB = CD

Given, distance between cow at C and cow at D = CD = 2 km

⇒ AB = 2 km

Hence distance between cow at A and cow at B is 2 km.

Direction: BSE stands for a disease called Bovine Spongiform Encephalopathy. “Bovine” means that the disease affects cows, “spongiform” refers to the way the brain from a sick cow looks spongy under a microscope, and “encephalopathy” indicates that it is a disease of the brain. This disease is commonly called “mad cow disease.”

A farmer has a field ABCD formed by two pair of parallel roads as shown below in which l ||m and p || q. His four cows suffering from BSE. Thus, he tied them at four corners of the field ABCD.

Q. If ∠B = 45°, then ∠D = _________ .

(opposite angles of a parallelogram are equal)

Q. If we join BD such that BD meet AC at O and ∠BOC = 30°, then what is the measure of ∠AOD?

(vertically opposite angles are equal)

Direction: A plane mirror is a mirror with a flat reflective surface.

An incident ray is a ray of light that strikes a surface. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface. In figure, m and n are two plane mirrors perpendicular to each other.

Q. Parallel lines :

• A. meet at a point
• B. never meet
• C. sometimes meet
• D. meet at right angle

Q. If BO = 3 cm, AB = 5 cm then, AO =

So, AO is perpendicular to BO.

Thus, triangle AOB is a right-angled triangle.

OA 2 + OB 2 = AB 2

OA 2 + 3 2 = 5 2

OA 2 + 9 = 25

OA 2 = 25 – 9 = 16

Q. Which statement is incorrect ?

• A. Corresponding angles formed at corresponding corners.
• B. Alternate interior angles are equal
• C. Angles on the same side of the transversal are complementary
• D. Vertically opposite angles are equal

Q. ∠DBA + ∠BAC

Therefore, they are supplementary.

Hence, ∠DBA + ∠BAC = 180°

Q. Incident ray CA is :

• A. parallel to AB
• B. perpendicular to BD
• C. parallel to BD
• D. perpendicular to AO

As mirrors are perpendicular to each other, therefore, BP || OA and AP || OB.

So, BP ⊥ PA, i.e., ∠ BPA = 90°

Therefore, ∠ 3 + ∠ 2 = 90° (Angle sum property) (1)

Also, ∠1 = ∠2 and ∠4 = ∠3 (Angle of incidence = Angle of reflection)

Therefore, ∠1 + ∠4 = 90° [From (1)] (2) Adding (1) and (2), we have

∠1 + ∠2 + ∠3 + ∠4 = 180°

i.e., ∠CAB + ∠DBA = 180°

Hence, CA || BD

Lines and Angles Class 7 Questions

Lines and angles Class 7 questions and solutions are given here in an easily understandable way. As we know, lines and angles are one of the important concepts of Class 7 maths, where you can learn the relationship between different angles and lines. In this article, you will learn how to solve lines and angles Class 7 questions using simple techniques.

What are Lines and Angles?

In geometry, we get a line when we extend the two endpoints in either direction endlessly. Angles are formed when lines or line segments meet each other at a common point.

Lines and Angles Class 7 Questions and Answers

1. Find the angle which is complementary to the following.

Two angles are said to be complementary if the sum of their measures is 90°.

The given angle is 45°.

Let x° be the measure of its complementary angle.

Then, x + 20° = 90°

x = 90° – 45°

Hence, the complement of the given angle measures 45°.

2. What measure of an angle is supplementary to the given angle?

Two angles are said to be supplementary if the sum of their measures is 180°.

The given angle is 105°.

Then, x + 105° = 180°

x = 180° – 105°

Hence, the supplementary of the given angle measures 75°.

3. An angle is greater than 45°. Is its complementary angle greater than 45° or equal to 45° or less than 45°?

Let x and y be the complementary angles.

We know that the sum of measures of the pair of complementary angles is 90°.

That means, x + y = 90°

It is given in the question that x > 45°.

Adding y on both the sides, we get;

x + y > 45° + y

90° > 45° + y

90° – 45° > y

4. In the given figure, identify:

(i) Five pairs of adjacent angles.

(ii) Three linear pairs.

(iii) Two pairs of vertically opposite angles.

From the given figure,

(i) Five pairs of adjacent angles are:

∠AOE and ∠EOC

∠EOC and ∠COB

∠AOC and ∠COB

∠COB and ∠BOD

∠EOB and ∠BOD

(ii) Linear pairs are:

∠AOE and ∠EOB

(iii) Vertically opposite angles are: ∠COB and ∠AOD

∠AOC and ∠BOD

5. Find the values of the angles x, y, and z in the following figure.

In the given figure,

55° and x are vertically opposite angles.

So, x = 55°

x and y are the linear pair of angles.

That means x + y = 180°

55° + y = 180°

y = 180° – 55° = 125°

Also, y and z are vertically opposite angles.

Thus, y = z = 125°

Therefore, x = 55°, y = 125° and z = 125°.

6. In the figure, find the value of z.

If a transversal cuts two parallel lines, then each pair of interior angles on the same

side of the transversal is supplementary.

So, z + 60° = 180°

z = 180° – 60° = 120°

Hence, the value of z is 120°.

7. In the below figure, p || q. Find the values of unknown angles.

d and 125° are corresponding angles.

We know that, the linear pair, i.e., the sum of adjacent angles is 180°.

That means e + 125° = 180°

e = 180° – 125°

e and f are vertically opposite angles.

So, e = f = 55°

Similarly, b = d = 125°

From the property of corresponding angles,

c = f = 55°

a = e = 55°

8. From the given figure, find the value of x.

As we know, the sum of all angles about a point is equal to 360°.

Then, 100° + 46° + 64° + x = 360°

210° + x = 360°

x = 360° – 210°

Therefore, the value of x is 150°.

9. In the figure, lines PQ and ST intersect at O. If ∠POR = 90° and x : y = 3 : 2, then find the value of z.

The sum of all angles about a straight line given in the figure, i.e., PQ is equal to 180°.

Then, ∠POR + ∠ROT + ∠TOQ = 180°

Given, x : y = 3 : 2

Let x = 3a, y = 2a

90° + 3a + 2a = 180°

90° + 5a = 180°

5a = 180° – 90°

So, x = 3a = 3 × 18° = 54°

y = 2a = 2 × 18° = 36°

From the figure SOT is a straight line,

Then, z + y = 180°

z + 36° = 180°

z = 180° – 36°

10. In the figure, PQ||ST. Find the value of x + 2y.

In the given figure, PO is a straight line.

As we know, the sum of angles on the straight line is equal to 180°.

y + ∠ PQR = 180°

y + 130° = 180°

∠QOS = ∠TSO [Co-interior angles]

Therefore, x + 2y = 85° + 2(50°) = 85° + 100° = 185°
