Longman Icse Mathematics Class 9. By Sehgal V.K. About this book · Shop for Books on Google Play. Browse the world's largest eBookstore and start reading. Get ready for Class 9 ICSE with the accurate study material prepared by our academic experts. The course content are prepared for all the subjects; Mathematics. In ICSE Class 9, Mathematics is one of the lengthiest and challenging subjects of all as it contains more than 38 chapters. The chapters given inside the textbook.
You learn how to figure out the values of unknown angles in a geometry composed by triangles. Properties like exterior angles, linear pairs, vertically opposite angles, alternate angles, etc. Suppose you see two similar objects and state to a friend that the two are geometrically same. But your friend refuses to believe so. How do you prove it?
Studying congruency of triangles provides with an insight on how you can do so. Here, you build the logic to prove that two triangular 2D bodies are a replica of each other, using Euclidean theorems. Named after Rene Descartes, this branch of mathematics that combines geometry with algebra is called Cartesian coordinate geometry. Plotting points in planes with its coordinates and notations is an essential concept covered in this chapter.
Line equations and Apollonius theorems are included as well. 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. Further, the chapter discusses the application of this formula to find areas of quadrilaterals. With the concept of the equation of a straight line, one can solve many other simple real-life problems. Linear equations are an essential tool to do the same. In this chapter, a student learns to present the geometric representation of various straight line equations.
A quadrilateral is a polygon with four edges and four vertices.
Here, you learn about the various properties of a quadrilateral and the relation between its angles. After developing the concept of convex and concave triangles, you get to solve problems involving a variety of quadrilaterals with unknown values of edges.
Formulae of area and volumes of different quadrilaterals are also introduced here. This chapter covers the formulae and methods of calculating the areas of various triangles and other parallelograms like rhombus and trapezium. One also learns their application by solving problems involving circles with other inscribed geometrical figures. In this chapter, you acquire the skills to construct geometric figures only using a scale and a compass.
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.
Even though we use the latest technology in interactive and live online education, the lessons maintain the personal touch and interaction of a traditional class environment. Students get familiar with their tutors who come with a very good reputation and expertise.
Our faculty comprises of leading teachers chosen from across the country — leaders in their respective fields. Class 9 students will get first-hand knowledge and tips from Ph. This kind of exposure is priceless at such an important juncture of school life. Along with high-quality resources like the RD Sharma class 9 solutions PDF free download, online classes in the core science subjects our website provide the best launch pad for students.
Chapter 1 — Number system The number system is a foundational concept, essential to progress with the rest of the class 9 math.
Chapter 2 — Exponents of real numbers Exponents, also called Powers or Indices, are a requisite concept for algebra.
Chapter 3 — Rationalisation An important concept for solving complex calculations without the help of a calculator, rationalisation helps you to convert a difficult-to-divide fraction into a simpler form. Chapter 4 — Algebraic identities Algebraic identities offer a shortcut to solving some of the cumbersome and lengthy problems.
Chapter 5 — Factorisation of algebraic expressions Factorisation is the opposite of expansion and is an essential concept for class 9 students.
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?
