what is the reduced portion for math ( algebra and geometry) for class 10 SSC Board for 2021 - 2022
Board has deleted some portion of the syllabus for the ease of students who will be taking their CBSE Board Exam.Here is the list of the CBSE Class 10 mathematics topics(Algebra and geometry) that are deleted from the original syllabus.
Algebra:
Polynomials-Statement and simple problems on division algorithm for polynomials with real coefficients.
Pair of linear equations in two variables-cross multiplication method.
Quadratic equations-situational problems based on equations reducible to quadratic equations.
Arithmetic progression-Application in solving daily life problem based on sum to n terms.
Coordinate geometry-area of a triangle.
Geometry:
Triangles-Proof of the following theorems are deleted . The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides. In a triangle, if the square on one side is equal to sumof the squares on the other two sides, the angle opposite to the first side is a right angle.
Circles-no deletion.
construction-construction of a triangle similar to a given triangle.

Hi Aspirant!
Co-ordinate geometry is considered one of the most important sections of the mathematics. It describes the link between algebra and geometry through graphs which involves curves and lines.
I am considering your query in the context of 11th and 12th class.
Chapters considered under co-ordinate geometry are:
- Introduction to 3D-Geometry - 11th class NCERT (Chapter 12)
- Three Dimensional Geometry - 12th class NCERT (Chapter 11)
Kindly note that to understand the basics of 3D geometry one should learn the complete basics of 2D geometry first.
Thankyou!
Will these problems of NCERT exemplar require any additional knowledge of Coordinate Geometry?
What are important 5 marks questions of 3D Geometry? Of Class 12th (2nd PUC) (For Board Exams) What are the Important Derivations of the same chapter?
Hello aspirant,
Here are 3 important questions:-
Q. 1: Find the direction cosines of the line passing through the two points (– 2, 4, – 5) and (1, 2, 3).
Q. 2: Show that the points A (2, 3, – 4), B (1, – 2, 3) and C (3, 8, – 11) are collinear.
Q. 3: If a line makes angles 90°, 135°, 45° with the x, y and z-axes respectively, find its direction cosines.
you may prepare these questions but you should also have a look to other questions also.
Hope this helps you
Feel free to ask any questions
All the best for your future
