Geometry

This chapter explains the concept of angles. It discusses types of angles such as adjacent angles, complementary angles, supplementary angles, vertically opposite angles, the concept of linear pairs and the exterior angle property of a triangle.

In this chapter, we will learn about the circle and its components. It explores the properties of a chord and congruent chords. It also explains the method to construct the incircle and the circumcircle of a triangle.

This chapter discusses the construction of the triangle if the lengths of the three sides are given. It also explains the property of the angle bisectors of a triangle, congruence of angles and bisector of an angle.

This chapter deals with the perimeter and area of different figures. It helps in learning how to construct boxes. Examples with illustrations are provided for clear understanding.

In this chapter, we will study right-angled triangles. Here, we will learn about Pythagoras theorem, finding the missing sides using Pythagoras theorem, applications of Pythagoras theorem and drawing right triangles with given lengths.
