Embibe Big Book for Mathematics for ICSE Class 8

Mathematics

Lines and Angles

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 topic discusses line-segment, ray, collinear and non-collinear points, arm, and vertex. It also explains acute, right, obtuse, straight, reflex, vertically opposite, adjacent, complementary, supplementary angles and linear pair of angles.

Basic Terms for Angles between Lines

From this topic, we will learn about the relationship of degree with minute and second. We will discuss what angle they all represent. Furthermore, we will be able to convert one unit or measure of an angle to the other via these relationships.

Lines and Angles: Types of Angles and Theorems

Differences in Linear Pair and Supplementary 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.

Triangles

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.

Volume and Surface Area of Solids

In this chapter, we will learn about perimeter and area. It explains the method of finding the perimeter and area of triangles and quadrilaterals. It also briefs on the circle, its circumference, and area of its sector.

Perimeter and Area of Plane Figures

In this chapter, we will learn about the concepts related to the circumference and area of a circle in detail. It explains how to find the wheel movement or motion along a circular track. It also briefs us on the annulus, along with some examples.

Circumference and Area of Circle

This chapter covers topics like introduction to symmetry, lines of symmetry, point symmetry, and rotational symmetry.

Idea of Symmetrical Shapes and Reflection Symmetry

This chapter details the methods to construct the isosceles, scalar and equilateral triangles in a stepwise manner. Here, we will learn to draw the triangle enclosed in a circle according to the given questions.

Constructions

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

Representing 3-D Shapes in 2-D

This chapter covers topics like parallelograms, properties of parallelograms, and theorems on parallelograms.

Parallelograms

This chapter covers topics like polygons, classification of polygons, properties of a polygon, and properties of quadrilaterals.
