You learn to construct various angles, bisect lines, inscribe triangles into figures and do much more. An easy yet scoring chapter, practising the problems here can lead you to get better grades tomorrow. A right circular cylinder is a commonly occurring geometrical figure in many other areas of science like physics and biology.

So, you need to learn the ways of measuring its dimensions. That is what you learn in this chapter. Here, a student learns to solve problems involving volume and surface area of a right circular cone. Learning the formulas for volumes of spheres is a part of the entire curriculum. The chapter falls under the topic of analytical geometry.

Statistics is the science of collection, presentation, analysis and interpretation of numerical data. Here, you are introduced to the basic concepts like primary and secondary data, discrete and continuous frequency distribution, etc. They offer a visual representation of statistical data. In this chapter, you learn about the different measures of central tendencies such as the mean, median and mode.

With these measures, you can identify the location of maximum number values in a distribution. Here, one understands the essential concepts like different types of events mutually exclusive, complementary, equally likely, etc. One also learns the theorems of compound probability, and other axioms and their application in solving complex problems. Students who enrol for our classes get to access their lessons from anywhere.

They get to learn from a comfortable home environment which allows for greater knowledge retention. They can also access their classes while they are in other locations because of the online platform. The flexibility is welcome and makes life less stressful for these young minds.

Chapter 6 — Factorisation of polynomials Most algebraic expressions take the form of a polynomial. Chapter 8 — Lines and angles Angles in a geometric figure form various relations with each other. Chapter 9 — Triangles and its angles Here, you are introduced to the various types of triangles and the properties of their three angles. Chapter 10 — Congruent triangles Suppose you see two similar objects and state to a friend that the two are geometrically same.

Chapter 11 — Coordinate geometry Named after Rene Descartes, this branch of mathematics that combines geometry with algebra is called Cartesian coordinate geometry. Chapter 12 — Herons Formula Useful in finding out the area of any triangle where only the length of its sides is given, Herons formula is an essential tool to learn.

Chapter 13 - Linear equation in two variables With the concept of the equation of a straight line, one can solve many other simple real-life problems.

Chapter 14 — Quadrilaterals A quadrilateral is a polygon with four edges and four vertices. Chapter 17 — Constructions In this chapter, you acquire the skills to construct geometric figures only using a scale and a compass.

Chapter 19 — Surface area and volume of a right circular cylinder A right circular cylinder is a commonly occurring geometrical figure in many other areas of science like physics and biology.

Chapter 20 — Surface area and volume of a right circular cone Here, a student learns to solve problems involving volume and surface area of a right circular cone. Chapter 21 — Surface area and volume of a sphere Learning the formulas for volumes of spheres is a part of the entire curriculum.

Chapter 22 — Tabular representation of statistical data Statistics is the science of collection, presentation, analysis and interpretation of numerical data. Chapter 24 - Measures of central tendencies In this chapter, you learn about the different measures of central tendencies such as the mean, median and mode. Why Vedantu?

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.

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.

Questions are very interesting and are based on real life or day to day incidents such as coin tossing, throwing a dice, deck of cards probability and simple events. This chapter is quite a fun to learn if you are curious enough to delve deeper.
