Geometry

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

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.

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

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.

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.

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).

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.

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.

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