Geometry

This chapter deals with the concept of triangles. It provides information on complementary angles, supplementary angles, and adjacent angles with the help of various examples and exercises.

This chapter explains the mid-point theorem. The mid-point theorem states that the line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.

In this chapter, we learn about Pythagoras theorem. It discusses the converse of Pythagoras theorem along with examples. It also contains exercises and important facts related to this concept. A historical note is also mentioned here.

This chapter sheds light on the concept of figures. It mainly focuses on rectilinear figures with examples and definitions. We will also learn about polygons and their different types and their constructions with the aid of diagrams.

This chapter discusses various theorems related to the area of a parallelogram, triangle, etc. It also briefs us about the area of equal figures. It also states that the sum of the areas of the smaller surfaces equals the area of the larger surface.

This chapter teaches us about the equation of a circle. It discusses the interaction between a circle and a line. It also provides information on parametric equations of a circle, pole and polar, and the coaxial system of circles.
