• Last Updated :06 Dec, 2021

CBSE Class 10 Mathematics Concepts, based on the latest syllabus for Class 10 Boards helps to understand all the concepts of class 10 maths chapter-wise. Notes provided by GeeksforGeeks comprise of all the formulae, theorems, concepts, proofs descriptions, definitions, graphs, that a student needs to practice and score good marks in their board examinations.

### Chapter 1: Real Numbers

The chapter Real numbers include both irrational and rational numbers with all natural numbers, whole numbers, integers, etc and discuss their characteristics.

### Chapter 2: Polynomials

Polynomials are algebraic expressions that consist of coefficients and variables or indeterminate. An arithmetic operation such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable can be performed on polynomials.

### Chapter 3: Pair of Linear Equations in Two Variables

An equation of the form ax+by+c, where a, b and c are real numbers and a, b are not equal to zero, is termed as the linear equation in two variables. However, in a pair of linear equations in two variables, there exist two such equations whose solution is a point on the line denoting the equation.

The degree 2 polynomial equations in one variable are called the Quadratic equations. The general form of a quadratic equation is ax2 + bx + c where a, b, c, ∈ R and a ≠ 0, where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of the complete equation.

### Chapter 5: Arithmetic Progressions

The arithmetic progression is explained as the sequence of numbers where the difference between any two subsequent numbers is a constant.

### Chapter 6: Triangles

Geometrically, a triangle is defined as a three-sided polygon consist of three edges and three vertices. The most important and applied property of a triangle is its Angle sum property which means the sum of the internal angles of a triangle is equal to 180 degrees only.

### Chapter 7: Coordinate Geometry

Coordinate Geometry is defined as the link between geometry and algebra using graphs along with the curves and lines. In this way, it provides geometric aspects in Algebra and leads to solve geometric problems.

### Chapter 8: Introduction to Trigonometry

Trigonometry can be defined as calculations including in triangles to study its lengths, heights and angles. Trigonometry and its functions have an enormous number of uses in our daily life.

### Chapter 9: Some Applications of Trigonometry

Trigonometry has a lot of practical applications in our real-life. This part of geometry discusses the line of sight, angle of deviation, angle of elevation, and angle of depression. Using trigonometry and trigonometric ratios the height of a building, or a mountain, from a viewpoint and the elevation angle can be determined easily.

### Chapter 10: Circles

A circle is a geometrical shape that is defined as the locus of points that move in a plane so that its distance from a fixed point is always constant. This fixed point is the Centre of the circle while the fixed distance from it is called the radius of the circle.

### Chapter 11: Constructions

Construction helps to understand the approach to construct different types of triangles for different given conditions using a ruler and compass of required measurements.

### Chapter 12: Areas Related to Circles

Area related to circles are the amount of space covered by a circle, which is defined in different ways. Some areas related to a circle are, area of the circle itself, Area of the sector, area of the segment, area of the triangle or parallelogram, etc located in a circle.

### Chapter 13: Surface Areas and Volumes

Surface area and volume are the measures calculated for a three-dimensional geometrical shape like a cube, cuboid, sphere, etc. The surface area of any given object is the area occupied by the surface of the object while volume is the amount of space available in an object.

### Chapter 14: Statistics

Statistics is the study of the representation, collection, interpretation, analysis, presentation, and organization of data. In other words, it is a mathematical way to collect, summarize data. The representation of data differently along with the frequency distribution.

### Chapter 15: Probability

The Probability in this class includes basic probability theory, which is also used in the probability distribution, to learn the possibility of outcomes for a random experiment and to find the probability of a single event to occur, when the total number of possible outcomes.
