Geometry

This chapter covers topics such as , Introduction to Coordinate Geometry & Cartesian System, Slope and Intercepts, Graphical Solution of Linear Equations, Graph of Linear Equations in two Variables, Distance Formula and its Application.

This chapter defines lines and angles. We will learn that a line is of infinite length that starts from infinity and ends at infinity. On the other hand, an angle is the combination of two non-collinear rays which meets at a common point.

This chapter defines triangles and describes their properties. A triangle is a shape which is formed by three non-parallel lines. The three corners of a triangle are known as three internal angles.

In this chapter, we will learn about quadrilaterals. A quadrilateral, sometimes also known as a tetragon or quadrangle (Johnson 1929), is a four-sided polygon. It states that all four polygon vertices are generally taken to lie in a plane.

In this chapter, we will study the various formulas that are used to find out the area of parallelograms and triangles. It discusses some properties of triangles and parallelograms. It also covers some examples for the detailed explanation.

The chapter introduces a circle and its characteristics. Further, it explains the set of those points in a plane which are equidistant from a fixed point in the plane.

This chapter talks about the techniques of construction. We will learn that construction involves the drawing of various shapes using only a pair of compass and straight-edge or ruler.

The chapter introduces Heron’s formula found in the year 60 AD. We will learn how this formula is helpful for us in conducting geometrical calculations.

This chapter deals with the concept of surface area and volume of three-dimensional figures. It consists of various formulae which are used to calculate the surface area and volume of a cube, cuboid, cylinder, sphere, cone, etc.
