Geometry

This chapter covers the fundamental concepts of geometry. It highlights the description of points, lines, curves and surfaces. We will come across closed and open figures. We will also study the difference between intersecting and parallel lines.

In this chapter, we will study the concept of angles and lines. It explains how to calculate the interior and exterior of an angle. The use of a protractor for measuring an angle is explained here. It also highlights the classification of angles.

This chapter discusses the construction of angles. We will come across the constructions using a ruler and a pair of compasses, and a ruler and the set squares. It also highlights the steps of construction of different angles.

In this chapter, we will come across the description of triangles. It highlights various properties of triangles. We will study different types of triangles with the help of figures here. It also covers the construction of triangles.

In this chapter, we will understand the different forms of quadrilaterals. It highlights the examples related to the angle-sum property of a quadrilateral. We will also come across types of quadrilaterals and their properties in detail.

This chapter describes a polygon by explaining the angles and angle property of a polygon. It highlights the figures for special polygons in tabular form. We will also study the difference between regular and irregular polygons via examples.

In this chapter, we will discuss the terms associated with circles. It explains the construction of circles with the help of various examples. We will also come across its different properties and learn how to apply them for solving questions.

This chapter is all about three-dimensional shapes. We will discuss the elements of 3D figures here. It highlights the method of obtaining the nets of 3D shapes via examples. We will also come across the difference between 2D and 3D shapes.

Through this chapter, we will come across the concept of symmetry. It explains how to identify symmetrical figures or objects. We will study the definition of linear and rotational symmetry via examples. It also covers the meaning of the line of symmetry.
