Course Content

CHATPETR – 1 NUMBER SYSTEM
The chapter named Number System helps the students to understand different types of numbers, different way to show the numbers (Rational & Irrational Numbers), how to show non-terminating repeating number in p/q form, how to show root 9.3 on number line. In this chapter student will also learn how to show different type of number (for example Rational, Irrational, Repeating).

CHATPETR – 2 POLYNOMIALS
The chapter named Polynomial, containing constant terms, variable terms, types of polynomials. In this chapter discussion takes place of relation between zeros and factor of the polynomials. In this chapter most important topic explained middle term split.

CHATPETR – 3 COORDINATE GEOMETRY
The chapter named Coordinate Geometry is completely based on 2D (Two – Dimensional), which is explained with graph. 2D is consisting of Abscissa, ordinate, x-axis, y-axis and four quadrants.

CHATPETR – 4 LINEAR EQUATIONS TWO VARIABLES
The chapter named linear equation helps the student how to draw the graph based on linear equation. Polynomials chapter helps to give students proper knowledge about the subject and the topic “Linear equations”. It also explains how to find solutions of a linear equation in two variables.

CHAPTER – 5 EUCLID’S GEOMETRY
Euclidean geometry is the study of geometrical shapes (plane and solid) and figures based on different axioms and theorems. It is basically introduced for flat surfaces or plane surfaces. Geometry is derived from the Greek words 'geo' which means earth and 'metrein' which means 'to measure'

CHATPETR – 6 LINES AND ANGLES
The chapter named Lines and Angles helps the students to learn the properties based on lines and angles and able to Identify and apply the properties of lines and angles. In this chapter Students learn angles made by the parallel and transversal lines for example (Corresponding angles, Alternate interior angles, perpendicular, complementary and supplementary angles, vertical angles)

CHATPETR – 7 TRIANGLES
The chapter named triangles helps the student to understand what the meaning of congruent is. It is also explained that what are the different criteria through which, we can say triangles are congruent { For example SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), RHS(Right angle-Hypotenuse-Side) }.

CHATPETR – 8 QUADRILATERALS
The chapter named quadrilateral helps the students to understand different shapes of polygon which has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

CHATPETR – 9 AREAS OF PARALLELOGRAMS AND TRIANGLES
The chapter named Area of Parallelogram and Triangles helps the students to understand the relation between area of triangle and a parallelogram if they are on a common base and between the same parallels lines. Students also learn to find the area of parallelogram and the scalene triangles.

CHATPETR – 10 CIRCLE

CHAPTER – 11 CONSTRUCTIONS
The chapter Named about construction helps the students to learn how to draw different types of angles and also helps to learn how to bisect the angles.

CHAPTER – 12 HERON’S FORMULA
The chapter named Heron’s formula helps the students to understand the formula. This formula can find the area of all types of triangles.

CHAPTER – 13 SURFACE AREA AND VOLUME
The chapter named surface area and volume helps the students to find the surface area of any given object is the area or region occupied by the surface of the object. This chapter also helps to find volume of given object which is the amount of space available in an object.

CHAPTER – 14 STATISTICS
About Statistics The chapter named statistics helps the students to do the study of the collection, analysis, interpretation, presentation, and organization of data. In other words, it is a mathematical discipline to collect, summarize data. Also, we can say that statistics is a branch of applied mathematics

CHPATER – 15 PROBABILITY
The chapter named Probability helps the students to understand Probability, which means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one, or it can be from 0% to 100%. Probability has been introduced in Maths to predict how likely events are to happen.
