3.1 Introduction

In earlier classes, you have studied Linear Equations in Two Variables. You have also studied that a Linear Equation in Two Variables has infinitely many solutions. In this chapter, the knowledge of Linear Equations in Two Variables shall be recalled and extended to that of Pair of Linear Equations In Two Variables.

Chapter 10 of NCERT textbook discusses the topic of Practical Geometry. You are familiar with a number of shapes. You learnt how to draw some of them in the earlier classes. For example, you can draw a line segment of a given length, a line perpendicular to a given line segment, an angle, an angle bisector, a circle etc. Now, you will learn how to draw parallel lines and some types of triangles. Topics covered in this chapter are the construction of a line parallel to a given line, through a point not on the line, construction of different types of triangles.

This chapter is about Simple Interest. In Class 6, you have already learnt perimeters of plane figures and areas of squares and rectangles. Perimeter is the distance around a closed figure while the area is the part of a plane or region occupied by the closed figure. In this class, you will learn about perimeters and areas of a few more plane figures. 006ab0faaa
