CBSE Class 10 Mathematics Syllabus 2019-2020

Check latest CBSE Class 10 Maths Syllabus to know which topics must be prepared for board exams. Students can also check the question paper design for class 10 Maths exam. Though, there will be two versions of Maths paper in board exam 2020, one easy and other standard level, syllabus for both types of papers remains common. So, all students are advised to refer the latest CBSE syllabus while they prepare for their internal exams like half-yearly and pre-board examinations or for the board exam 2020.

Contents of CBSE Class 10 Maths syllabus 2019-2020 are:

• Unit-wise weightage
• Topics and sub topics to be prepared from each unit
• Question paper design for the annual board examination
• Components of Internal Assessment
• Prescribed books

CBSE has introduced certain changes in the Maths question paper structure for board exam 2020. About 25% of the questions will be objective type questions carrying 1 mark each. Students may check the latest CBSE Class 10 Sample Papers 2020 to understand the format of question paper for board exam 2020. However, to know the typology of questions, go through the question paper design given in CBSE syllabus for class 10 Maths. It will be quite helpful to structure your study plan and work in a productive way.

1. (Prove) 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.

2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.

3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.

4. (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.

5. (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.

6. (Motivate) If a perpendicular is drawn from the vertex of the right angle of a right triangle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other.

7. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.

8. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.

9. (Prove) 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.

2. Circles (8 Periods)
