Basically, Ratio represents the relationship between the two numbers which indicates how many times the first number contains the second. Proportion is also related to the concept of ratio.
In this chapter, you will also learn the concept of the unitary method. This method is used to find the required value with the help of-of the value of any single unit. Chapter 11 - Line Segment, ray and Line The chapter the comprehensive guide to the topics like a line segment, Ray and the line.
After going to the exercises you can easily differentiate between the line segment, Ray and line. These topics are covered step by step to give you strategic knowledge to deal with the problems of line and Ray. Remember, the main difference between the Ray and line is that a Line goes infinite in both the direction but stops on one end.
Chapter 12 - Parallel Lines Those two lines which always remains at the same distance from each other but never touch are known as parallel lines. The great example of parallel line in a railway track. The concept of parallel lines is explained inside the exercises in detail with more effective examples.
Chapter 13 - Angles and their measurement In this chapter, you will learn how to measure the angles and the various concepts related to the angles. This chapter makes the use of geometric tools like protector, scale and divider etc. Various types of angles are also described in this chapter.
The exercises in this chapter are based on Acute, obtuse, straight and right angles. Apart from the types of angles chapter covers more. Chapter 14 - Constructions Construction is the process of drawing shapes, angles or lines accurately with the help of three tools called compass, ruler and a pencil. So in this chapter, you will learn how to construct different angles with the help of some basic geometric tools. After doing the exercises your all doubts regarding the Constructions in mathematics will be cleared.
Chapter 15 - Polygons Polygon is a two-dimensional shape formed with the help of straight lines. The most common examples of the polygon are Triangles, quadrilateral, Pentagon and hexagon etc. So in this chapter, you will understand the concept of polygons in detail. Angles of the polygons and the sides endowed with more importance inside the chapter. Chapter 16 - Triangles Triangle is one of the basic shapes in geometry.
If we understand the triangle in simple terms, a triangle is a polygon having three edges and three vertices.
You will study different types of triangles in this chapter. Acute triangles, obtuse triangles and right angle triangles are the three main types of triangles that you are going to study.
Living in the Light: A guide to personal transformation
Foreign knowledge, Triangles have an important role in the construction of bridges and the architecture field. Chapter 17 - Quadrilaterals A quadrilateral is a polygon which has four edges and four vertices.
In mathematics, there are different types of quadrilaterals. Rectangle, square, rhombus and parallelogram etc are some of the examples of quadrilaterals. In this chapter, the exercises are going to be the comprehensive guide to the quadrilaterals and ultimately help you to understand the concept of various quadrilaterals. Chapter 18 - Circles The circle is a collection of all the points which are equidistant from a single point and this single point is known as the centre of the circle. So basically, this chapter covers the concepts of radius and diameter etc of the circle.
By going through the exercises you will get the practical knowledge of the circle. Chapter 19 - Three-Dimensional Shapes According to the geometry, three-dimensional shape is defined as of solid figure which has three dimensions - length, width and height. Cube, cuboid and cone etc are the examples of three-dimensional shapes. This chapter is a detailed discussion about the three-dimensional shapes and the exercises also cover the same.
Chapter 20 - Two-Dimensional Reflection Symmetry After the flipping of two or more parts of an object, and if these parts are found identical then the symmetry is achieved.
This chapter is all about the symmetry, so show the exercises includes tough problems related to the symmetry of the object.
You are going to understand the lines of symmetry inside the various figures. Chapter 21 - Concept of Perimeter and Area The total distance around the edge of any figure is termed as the perimeter. The number of units of the square that can be contained inside a plane figure is known as the area. So in this chapter, the concept of perimeter and the area of the shapes have been described in detail.
You will understand how is square is also a type of rectangle. Chapter 22 - Data Handling Data handling is the process of observing the data and making it in in such a way that anyone can analyse it to get desired results. Data handling is one of the most serious and complex actions in the field of mathematics.
In this chapter, you will learn about the management of data and arranging it in such a way to get the desired result in the form of generalities or recurring patterns. Chapter 23 - Pictograph When the collected data is represented by the symbols and pictures, it is termed as a pictograph.
The advantage of using pictograph is that at a large amount of data can be represented in well-simplified form and it gives all the necessary information clearly and quickly. So this chapter is all about pictograph, exercises are well curated to make you understand the concept of pictograph.
Chapter 24 - Bar Graph The bar graph is a method of representing data on the graph by making the use of bars of different heights. It depends on the variables of the data represented that which type of alignment will be used in bars. Basically, there are two types of alignments, horizontal and vertical.
The use of bar graph makes it easy to compare data which is not possible in a regular graph. These rational numbers will be making our mathematics easier, and we can acknowledge significant calculations. Chapter 2 Exponents Exponents are the all-new concept which will be there for you to make you understand how significant number which cannot be evaluated and is shortened and it becomes easier for them to figure. We need to make a big amount of perceptive for more significant calculations.
In this chapter, you will also learn how exponents also need to obey some rules. Exponents rules are also different for odd and even numbers. Chapter 3 Square and square roots This chapter is designed to teach students about square and square roots.
After solving the question from this chapter, the students will know to find the square and square roots of a given number. To practice more questions based on rectangular and square roots, students are advised to solve the RS Aggarwal for class 8 solutions. You will understand class 8 methods which are going to be helpful in professional classes. Chapter 4 Cube and cube roots In this chapter, the students of the 8th standard will also learn the basic concepts of cubes and cube roots.
After solving the questions of this chapter from RS Aggarwal for class 8 students will learn how to calculate the cube roots and hub of a given number. To help students, we have also provided the RS Aggarwal class 8 solutions chapter 4 cubes and cube roots in it.
Chapter 5 Playing with numbers RS Aggarwal class 8 solutions chapter 5 playing with Number is provided here. In this lesson, the students will understand how to find the missing number in a sum or a subtraction problem. To answer all the questions asked from this chapter and to understand the chapter students are advised to solve issues from RS Aggarwal for class 8, it is a fun filled and important chapter.
Chapter 6 Operation on Algebraic Expressions An algebraic expression is a world full of variables and constants, and in this, you add, multiply, divide and subtract everything, and this will make you understand the puzzles of mathematics.

In this chapter, the students will learn factorisation by regrouping terms and factorisation using identities.
Learning these concepts in class 8 will help students to understand advanced concepts in higher and professional course so get the concepts clear. Chapter 8 Linear equations Equation talks about two expressions which occur at the same time have a different type of values. Whenever we are dealing with balanced equations despite subtracting, adding, multiply or divide the value of the equation remains the same, and the balance stays. There will be a new concept of transposing; it means you will learn to move the number to the other side.
There you will also understand about building a practical puzzle with the help of the equation.
Chapter 9 Percentage Anything which refers to means percentage. Whenever we deal with s, we talk in percentage instead of pointing out the s.
