Geometry

In this chapter, we will learn about similar figures, similarity of triangles, how to calculate the area of triangles, etc. We will also learn the Pythagoras theorem.

In this chapter, we review the concepts of geometry and graphs of linear equations related to coordinate geometry. We learn the formula of distance between two points, collinear points, section formula, centroid and area of a triangle.

The chapter emphasizes the concept of the circle and its properties. It also demonstrates the distinct parts and methods of construction through activities and sample examples discussed here through diagrams.

In this chapter, you will learn about constructions by using the knowledge attained while studying in earlier classes. Justification of using various concepts of geometry is also provided here.

This chapter discusses problems on finding areas of two special parts of a circular region: sectors and segments of a circle. It also discusses problems on finding areas of some combinations of plane figures involving circles or parts of circles.

This chapter discusses problems on finding surface areas and volumes of solids. We will also come across solids, which are a part of a cone known as frustums of a cone. Problems on surface areas and volumes of frustum are also provided.
