Quick Revision Notes – Ncert 10 Maths Book Pdf

• Chapter 1 focuses on proving irrationality of numbers like √2, √3, √5 using contradiction method – remember the standard steps for board exam proofs.
• For polynomials, if p(x) is divided by (x-a), remainder is p(a); this remainder theorem is frequently tested in 3-mark questions.
• Linear equations graphically: parallel lines (no solution), intersecting lines (unique solution), coincident lines (infinite solutions).
• Quadratic equations can be solved by factorization, completing square, or quadratic formula – practice all three methods for different question types.
• In AP problems, always identify whether you need to find term, sum, or number of terms, then apply appropriate formula.
• Triangle similarity criteria: AAA, SSS, SAS – construct proper diagrams and mark equal angles/proportional sides clearly.
• Coordinate geometry section formula and area of triangle using coordinates are high-scoring topics in board exams.
• Memorize trigonometric ratios for 0°, 30°, 45°, 60°, 90° – these values appear in multiple chapters including heights and distances.
• Heights and distances problems require proper diagram drawing and identifying which trigonometric ratio to use.
• Circle chapter theorems must be stated exactly as given in NCERT – learn theorem statements word-by-word for board exams.
• Construction problems carry 4 marks each – practice steps for angle bisectors, perpendicular bisectors, and tangent constructions.
• Mensuration formulas for surface areas and volumes should be memorized with proper units for numerical problems.
• Statistics: for median calculation in grouped data, identify median class first using N/2, then apply interpolation formula.
• Probability problems in CBSE often involve cards, dice, or balls – clearly define sample space and favorable outcomes.
• Practice previous year board papers to understand marking scheme and time management for 80-mark mathematics paper.
