Geometry

This chapter defines point, line, plane, line segment, ray, concurrent lines and collinear points. We will learn about angles and types of angles. It also explains how to find the measure of unknown angle with the aid of examples.

This chapter explains how to construct various angles based on various conditions. We will learn to bisect a given angle with the aid of examples. It also explores the steps to draw a perpendicular line to a given line.

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.

This chapter explains point, line and rotational symmetry with the aid of examples. It briefs on the properties of reflection of an object in a plane mirror. We will also learn in detail the rules for reflection.

This chapter covers topics like solid shapes, faces, edges and vertices, nets for building 3D shapes, drawing solids in flat surface (2D drawing of a 3D), viewing different sections of a solid, and mapping.

This chapter sheds light on the perimeter and area of various 2-D figures. We will learn how to find the area and perimeter of a square, rectangle and triangle. It also discusses the applications of perimeter and area.

In this chapter, we will learn about co-ordinate axes along with their definition and notation. Convention of sign and points on the axes is also described here. We will also learn how to find the co-ordinates of each point on the graph.

In this chapter, we will learn about polygons. It unfolds the notion of triangles and quadrilaterals. We will also explore the properties and shapes of square, rectangle, rhombus and parallelogram.

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.

In this chapter, we will learn how to find the volume and surface area of cubes and cuboids. It teaches us how to find the area of four walls of a room. It also comprises exercises based on finding the volume and surface area of cubes and cuboids.
