Geometry

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

This chapter describes the concept of measurement of line segment and angles. It briefs on directions, degrees, minutes, and seconds. We will also learn different types of angles, triangles, quadrilaterals, and polygons.

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.

In 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.

This chapter discusses the construction of circles, perpendicular lines, and angles. It explains how to draw a line perpendicular to a given line from a point. It also highlights the angles of special measures.
