CBSE Class 9 Maths Chapter 15 Probability Notes

1. Some Basic Definitions (i) Trial: A single performance of a random experiment is known as a trial. (ii) Sample space: The set consisting of all possible outcomes of a random experiment is known as sample space. (lii) Event: A subset of the sample space of a random experiment is called an event. 2. Probability: Let n be the total number of trials and […]

CBSE Class 9 Maths Chapter 14 Statistics Notes

1. Primary and Secondary Data: When the information was collected by the investigator herself or himself with a definite objective in her or his mind, the data obtained is called primary data. When the information was gathered from a source which already had the information stored, the data obtained is called secondary data. 2. Raw Data: Let us consider […]

CBSE Class 9 Maths Chapter 13 Surface Areas and Volumes Notes

1. Cuboid: A figure which is surrounded by six rectangular surfaces is called cuboid. The opposite surface of a cuboid is equal and parallel. A cuboid has 12 edges and 8 corners. Each corner of a cuboid is called the vertex of a cuboid. The line segment joining the opposite vertices is called the diagonal of a […]

CBSE Class 9 Maths Chapter 12 Constructions Notes

1. Need of Accurate Figures: Sometimes one needs an accurate figure, for example, to draw a map of a building to be constructed, to design tools and various parts of a machine, to draw road maps, etc. To draw such figures some basic geometrical instruments are needed. 2. Geometry Box: A geometry box contains the following basic geometrical instruments […]

CBSE Class 9 Maths Chapter 11 Circles Notes

1. Circle: The collection of all points in a plane which are at a fixed distance from a fixed point in the plane is called a circle. The following examples of the circle are 2. Basic Definition Chord: Suppose, we take any two points on a circle, then the line segment PQ is called the chord of the […]

CBSE Class 9 Maths Chapter 10 Areas of Parallelograms and Triangles Notes

1. Congruent Figures: Two figures are called congruent if they have the same shape and same size. If two figures X and Y are congruent (see adjoining figure), then using a tracing paper we can superpose one figure over the other such that it will cover the other completely. So, if two figures X and Y are […]

CBSE Class 9 Maths Chapter 9 Quadrilaterals Notes

1. Quadrilateral: A plane figure bounded by four lines segment AB, BC, CD and DA is called a quadrilateral. The sum of the angles of a quadrilateral is 360°. 2. Various Types of Quadrilaterals (i) Parallelogram: A quadrilateral in which opposite sides are parallel is called parallelogram and it is written as Parallelogram. (ii) Rectangle: A parallelogram each of whose angle […]

CBSE Class 9 Maths Chapter 8 Linear Equations in Two Variables Notes

Linear Equations: Any equation which can be put in the form ax + by + c = 0, where a, b and c are real numbers and a and b are not both zero is called a linear equation in two variables. The solution of a linear equation is not affected when the same number is […]

CBSE Class 9 Maths Chapter 7 Heron’s Formula Notes

1. Triangle: A plane figure bounded by three line segments is called a triangle. In ΔABC has (i) three vertices, namely A, B and C. (ii) three sides, namely AB, BC and CA. (iii) three angles, namely ∠A, ∠B and ∠C. 2. Types of Triangle on the Basis of Sides (i) Equilateral triangle: A triangle having all sides equal […]
