Geometry

In this chapter, we will explore different geometrical shapes. We will learn the concept of point, line segment, line, ray and curve. In addition, we will learn about angle, triangle, quadrilateral and circle.

In this chapter, we will learn to measure the different geometrical shapes such as lines, angles, circles, and so on. We will study the comparison of the line segment by various instruments. It also discusses the different types of angles.

This chapter describes perimeter and area as measures to compare the sizes of different shapes. It explains the perimeter of a rectangle, perimeter of a regular shape, area of a rectangle and area of a square.

This chapter helps us to identify the line of symmetry and rotational symmetry of simple geometrical figures. We will also learn to identify the angle of rotation and order of rotation in 2D figures with the help of several examples.

This chapter explains how to measure the sides and angles by ruler and protractor. It introduces the construction of line segments with a ruler and compass, construction of a circle, perpendicular lines, and constructing lines of different angles.

In this chapter, the concepts related to 2D and 3D shapes and their visualization is explained in detail. We will learn about the nets of 3D solids. It also describes how to draw three-dimensional solids and to view the different sections of a solid.
