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 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.

We have studied that a circle is a collection of all points. In this chapter, we will learn about the existence of the tangents to a circle and study their properties.

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

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.
