Part 1

This chapter discusses the concepts of rational and irrational numbers. It explains the decimal representation of rational numbers. We will also learn to compare the rational numbers.

This chapter covers the concept of transversal and the angles constructed by a transversal. It explains the properties of angles formed by parallel lines and transversals. It also discusses how to draw a line parallel to a given line.

In this chapter, we will study the meaning of numbers along with rational indices and their properties. It explains the meaning of cube and cube root. It further explains the method of finding the cube root of the numbers.

In this chapter, we will focus on the concept of altitude and its steps of construction. It illustrates the median and the property of the centroid of a triangle. We will also learn about the orthocentre of a triangle.

In this chapter, we will understand the expansion method using various equations. It discusses the steps of simplification with the aid of practice sets and examples.

In this chapter, we will focus on factorisation of algebraic expressions. It discusses the rational algebraic expression and its properties. We will also learn about the factors of a quadratic trinomial.

This chapter explains the meaning of direct and inverse variation. It discusses the variation related to time, work, and speed. We will also learn the application of direct and inverse variation to solve the questions.

In this chapter, we will learn the steps to construct a quadrilateral through various examples. It also discusses rectangles, squares, rhombuses, and trapeziums with the help of illustrations.

In this chapter, we will learn the concepts of discount and commission. With the help of solved examples, we will learn to calculate discounts and commission based on the price of a given object.
