Part One

In this chapter, we will learn to construct an angle bisector, the perpendicular bisector of a line segment, and a triangle and their properties. It also explains the concept of congruence of circles, angles, and segments.

This chapter explains the concept of multiplication and division of integers. Here, we will get to solve various exemplar problems for a better understanding of the concept.

In this chapter, we will learn the concepts of HCF and LCM. It explains twin prime numbers, prime factors method, and division method for finding the HCF, and the use of HCF and LCM.

In this chapter, we will learn the properties of angles. It covers the adjacent angles, supplementary and complementary angles. It also discusses vertically opposite angles, linear pair, interior and exterior angles of polygons and triangles.

In this chapter, we will study the operations on rational numbers. We will learn to find numbers in between the given rational numbers, the decimal form of rational numbers, and rules for simplifying an expression.

This chapter explores the concept of indices. It describes the terms base, index, squares and cubes of numbers and explains multiplication and division of indices with the same base. It also discusses the index of the product.

This chapter deals with the concept of joint bar graphs. Here, we will learn to read and draw joint bar graphs step-wise with the help of examples.

In this chapter, we will learn the algebraic expressions and operations on them. Here, we will explore different algebraic expressions and their addition, subtraction, multiplication and division. It also covers equations in one variable.
