## CBSE Class 10 Maths Syllabus 2020-21| Check Latest Exam Pattern

CBSE Class 10 Maths Syllabus 2020-21 has been released officially. Before starting the session, you must need to look at the latest exam pattern to assess yourself effectively. The Maths has been divided into two parts just like previous session into basic and standard. Last year, students who opted for Basic Mathematics are low but CBSE still continued this part.

Due to Coronavirus, CBSE has decided to reduce the syllabus by approx 30% overall and this affected Maths syllabus also. There are variety of topics that have been deleted from the syllabus.

Units | Unit Name | Marks |

I | Number Systems | 06 |

II | Algebra | 20 |

III | Coordinate Geometry | 06 |

IV | Geometry | 15 |

V | Trigonometry | 12 |

V | Mensuration | 10 |

VI | Probability | 11 |

Total | 80 |

â€¢ If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

â€¢Â The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.

â€¢ In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

â€¢ In a triangle, if the square on one side is equal to sum of the squares on the other two sides, the angles opposite to the first side is a right angle.

â€¢ The tangent at any point of a circle is perpendicular to the radius through the point of contact.
