Chapter 2: Polynomials This chapter explains the algebraic expression called polynomial and the detailed terminologies related to it very clearly.
With a total of 4 exercises, you will be learning plenty of examples and definition of a polynomial, degrees, coefficient, zeroes and terms of a polynomial. Types of Polynomials - Linear, Constant, quadratic and cubic polynomials, monomials, binomials, trinomials.
Factors and multiples, Remainder and factor theorems, factorization of a polynomials using factor theorem. Chapter 3: Coordinate Geometry Chapter 3 has a total of 3 exercises in this chapter called Coordinate Geometry.
You will be studying the concept of cartesian plane, coordinates of a point in this xy — plane, name, terms, notations and other terms associated with the coordinate plane. Abscissa and ordinate of a points. You will learn to Plot a point in xy — plane and the process of naming it.
You will see a total of 4 exercises in this chapter with questions related to Proving a linear equation has infinite number of solutions, plotting a linear equation on graph and justification of any point on line.
With a total of two exercises, you will be delving deeper into relationship between axiom, postulates and theorems. Chapter 6: Lines and Angles With two exercises in total, this chapter has theorems in Lines and Angles chapter which may be asked for proof.
Rest of the theorems are given for motivations and questions will be asked on the basis of all these theorems. Chapter 7: Triangles In Chapter 7, Triangles of class 9 Maths, you will study the congruence of triangles in details along with rules of congruence. Also, there are many more properties of triangles and inequalities in a triangle to learn in this chapter. Chapter 8: Quadrilaterals The chapter Quadrilaterals consists of only two exercises.
However, it is a very interesting chapter with only one theorem for proof. Others will be asked in the form of application and conceptual questions. Questions in quadrilaterals are on the basis of properties of quadrilaterals and combinations of it with triangles.
Chapter 9: Areas of Parallelograms and Triangles This chapter explains the meaning of area right from the introduction part. Areas of parallelograms and triangles and their combinations given in this chapter to will be asked to prove in most of the questions. Example of median may be used as theorem in most of the questions. The other important theorems prove to be helpful for solving questions based on triangle, quadrilateral and circles. Chapter Constructions With a total of just two exercises, you will be learning two categories of constructions.
One is Construction of bisectors of the line segments and angles of measure including 60, 90, 45 etc. What all you will be learning in this chapter is just the extension of concepts related to area of triangle. Knowledge of formulae of plane figures is also imparted in this chapter which will help in doing questions.
Chapter Surface Areas and Volumes Students are well aware of surface areas and volumes as they have already studies mensuration in earlier classes.
This chapter also have problems based on surface areas and volumes of cube, cuboids, cylinders, cones, spheres and hemispheres. Conversion of one of the figures into the another, comparing volumes is also given as an application of mensuration.
Chapter Statistics Description of statistics in this chapter is explained simply as the collection of data on different aspects of the life of people, which is useful to the State and interpretation and drawing of inferences from the data. With a total of four chapters, Introduction to statistics includes the presentation of data collected in a raw form. Building blocks of this chapter are presentation of data in tabular form by grouping them in a regular intervals, histogram or polygon, bar graph drawing.
Topics like how to find the measure of central tendency mean and mode and median of raw data.
Chapter Probability With only one exercise, Probability of class 10 Maths is based on the frequency or the observation approach. Total number of students in mathematics is The data is recorded in the following table.
Find the probability that a student chosen at random i likes statistics, ii does not like it. What is the empirical probability that an engineer lives : i less than 7 km from her place of work?
Find the probability that any one vehicle out of the total vehicles you have observed is a two wheeler. Activity problem : Collect the data and find the desired probability. Choose any student from the room at random.
Remember that a number is divisible by 3, if the sum of its digits is divisible by 3. Activity problem : Do as directed and find the desired probability. Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.
