NCERT Solutions for Class 10 Maths: All Chapters at a Glance

The Class 10 NCERT Maths textbook consists of 15 chapters that are carefully structured to progress from foundational number concepts to statistics and probability. Here is a complete chapter-by-chapter overview:

Chapter 1: Real Numbers

Key Topics: Euclid's Division Lemma, Fundamental Theorem of Arithmetic, Irrational Numbers, Decimal Expansions

Real Numbers is typically the first chapter tackled in Class 10, and it lays the logical foundation for higher mathematics. A common exam question involves proving that √2 or √3 is irrational — a concept our solutions explain through contradiction-based proofs in simple steps.

Important Concepts to Master:

  • Euclid's Division Algorithm to find HCF
  • Prime factorisation to find LCM and HCF
  • Proving irrationality of numbers
  • Terminating and non-terminating decimals

Myclass24 Tip: Focus on understanding Euclid's Lemma intuitively. Board exams frequently ask 2–3 mark questions on HCF using the division algorithm.

Chapter 2: Polynomials

Key Topics: Zeroes of a Polynomial, Relationship between Zeroes and Coefficients, Division Algorithm for Polynomials

Understanding polynomials is essential because the concept carries forward into higher grades. This chapter covers quadratic and cubic polynomials with graphical representations.

Important Concepts to Master:

  • Finding zeroes of quadratic polynomials from graphs
  • Sum and product of zeroes (α + β and αβ)
  • Forming a quadratic polynomial when zeroes are given
  • Polynomial division using the remainder theorem

Myclass24 Tip: Memorise the relationships α + β = –b/a and αβ = c/a — these appear in nearly every exam paper.

Chapter 3: Pair of Linear Equations in Two Variables

Key Topics: Graphical Method, Substitution, Elimination, Cross-Multiplication, Reducible Equations

This chapter introduces students to solving real-world problems by setting up equations with two unknowns. It is a highly application-based chapter and one of the most scoring in board exams.

Important Concepts to Master:

  • Consistent, inconsistent, and dependent pairs
  • Graphical interpretation of solutions
  • Algebraic methods: substitution and elimination
  • Word problems (age, speed, mixture, money)

Myclass24 Tip: Practice at least 10 word problems per week. Board exams always include one 3-mark or 4-mark application problem from this chapter.

Chapter 4: Quadratic Equations

Key Topics: Standard Form, Factorisation, Completing the Square, Discriminant (D = b² – 4ac)

Quadratic Equations is a chapter that connects algebra to real-world scenarios like projectile motion and area problems. The quadratic formula and nature of roots are essential board exam topics.

Important Concepts to Master:

  • Solving by factorisation
  • Solving by completing the square
  • Using the quadratic formula
  • Nature of roots: D > 0, D = 0, D < 0

Myclass24 Tip: Don't skip "completing the square" — it helps you understand where the quadratic formula comes from and may appear as a derivation question.

Chapter 5: Arithmetic Progressions (AP)

Key Topics: nth Term, Sum of n Terms, Arithmetic Mean

Arithmetic Progressions is one of the most formula-heavy chapters and also one of the most scoring. Students from across India consistently rank it among their favourite chapters due to the pattern-recognition involved.

Important Concepts to Master:

  • General term: aₙ = a + (n – 1)d
  • Sum of n terms: Sₙ = n/2 [2a + (n – 1)d]
  • Finding the number of terms
  • AP-based word problems (savings, rows of seats, etc.)

Myclass24 Tip: If you are given Sₙ, remember that aₙ = Sₙ – Sₙ₋₁. This trick saves time in board exams.

Chapter 6: Triangles

Key Topics: Similar Triangles, Criteria for Similarity (AA, SAS, SSS), Basic Proportionality Theorem (Thales' Theorem), Pythagoras Theorem

Triangles is a high-weightage geometry chapter and regularly contributes to long-answer (5-mark) questions. Proofs are a core component here.

Important Concepts to Master:

  • Basic Proportionality Theorem and its converse
  • Criteria for similarity of triangles
  • Areas of similar triangles
  • Proof of the Pythagoras Theorem

Myclass24 Tip: Learn the proofs for Thales' Theorem and Pythagoras' Theorem thoroughly. Board examiners frequently ask for these as 5-mark proofs.

Chapter 7: Coordinate Geometry

Key Topics: Distance Formula, Section Formula, Area of a Triangle

Coordinate Geometry bridges algebra and geometry by placing geometric shapes on a number plane. It is extremely formula-driven and very scoring.

Important Concepts to Master:

  • Distance between two points: √[(x₂ – x₁)² + (y₂ – y₁)²]
  • Section formula (internal and external division)
  • Midpoint formula
  • Area of a triangle using coordinates

Myclass24 Tip: Sketch a rough diagram before solving any coordinate geometry problem. It helps you avoid sign errors.

Chapter 8: Introduction to Trigonometry

Key Topics: Trigonometric Ratios, Reciprocal Identities, Trigonometric Ratios of Standard Angles, Complementary Angles

Trigonometry is a cornerstone of Class 10 Maths. Students preparing in cities like Surat, Nagpur, Visakhapatnam, and Coimbatore often find this chapter challenging, but with the right approach and consistent practice, it becomes one of the most manageable.

Important Concepts to Master:

  • sin, cos, tan, cosec, sec, cot and their relationships
  • Values at 0°, 30°, 45°, 60°, 90°
  • Complementary angle identities
  • Proof-based identity questions

Myclass24 Tip: Create a table of trigonometric values and paste it where you study. Daily revision of these values will make the chapter significantly easier.

Chapter 9: Some Applications of Trigonometry

Key Topics: Heights and Distances, Angle of Elevation, Angle of Depression

This chapter applies the trigonometric ratios learned in Chapter 8 to practical, real-world scenarios involving angles of elevation and depression.

Important Concepts to Master:

  • Setting up the correct right-angled triangle from a word problem
  • Using tan θ for height/distance problems
  • Problems with two angles of elevation or depression
  • Shadow and ladder problems

Myclass24 Tip: The most common mistake here is confusing angle of elevation with angle of depression. Always draw a diagram first.

Chapter 10: Circles

Key Topics: Tangents to a Circle, Number of Tangents from a Point, Theorem on Equal Tangents

Circles introduces elegant geometric theorems that require logical reasoning and proof. It is a compact yet high-scoring chapter.

Important Concepts to Master:

  • Tangent is perpendicular to the radius at the point of tangency
  • Lengths of tangents drawn from an external point are equal
  • Proof-based questions involving tangents and chords

Myclass24 Tip: Practice all NCERT proofs from this chapter. Board questions almost always pick from the theorem-proof exercises.

Chapter 11: Constructions

Key Topics: Division of a Line Segment, Construction of Tangents to a Circle

This chapter requires practical skills. Students are expected to use a compass and ruler to construct geometric figures accurately.

Important Concepts to Master:

  • Dividing a line segment in a given ratio
  • Constructing a triangle similar to a given triangle
  • Drawing tangents to a circle from an external point

Myclass24 Tip: Practice each construction at least 5 times. Accuracy and labelling carry marks in the board exam.

Chapter 12: Areas Related to Circles

Key Topics: Perimeter and Area of Circles, Sector, Segment, Combination of Figures

This is a practical application chapter where students calculate areas of sectors, segments, and combined figures involving circles and polygons.

Important Concepts to Master:

  • Area and perimeter of a sector
  • Area of segment = Area of sector – Area of triangle
  • Problems involving rings, paths, and combination shapes
  • Using π = 22/7 or 3.14 as directed

Myclass24 Tip: Always check whether the question asks for the minor or major segment. Mixing these up is a very common error.

Chapter 13: Surface Areas and Volumes

Key Topics: Combination of Solids, Conversion of Solids, Frustum of a Cone

This is one of the most formula-intensive chapters and carries significant weightage in CBSE board exams. Students from Tier-1 and Tier-2 cities alike often cite this as a chapter where they lose marks due to formula confusion.

Important Concepts to Master:

  • Surface area and volume of combination solids (cone + hemisphere, cylinder + cone, etc.)
  • Conversion of one solid to another (e.g., a sphere melted into small spheres)
  • Frustum: volume and lateral surface area
  • Word problems involving real-world contexts (water tanks, toys, etc.)

Myclass24 Tip: Make a formula sheet for all 3D shapes. Refer to it every day for two weeks before the board exam.

Chapter 14: Statistics

Key Topics: Mean, Median, Mode of Grouped Data, Cumulative Frequency, Ogive

Statistics is a data-heavy chapter that is also highly practical. It teaches students to interpret and analyse real-world data — a skill increasingly important in today's world.

Important Concepts to Master:

  • Mean by direct, assumed mean, and step-deviation methods
  • Median using the formula and ogive (less than / more than)
  • Mode of grouped data
  • Drawing and interpreting cumulative frequency curves

Myclass24 Tip: Practice drawing ogives accurately. A 5-mark question from Statistics almost always involves the cumulative frequency graph.

Chapter 15: Probability

Key Topics: Classical Probability, Complementary Events, Cards, Dice, Coins

Probability is the final chapter and a favourite among students because it involves straightforward logic and everyday scenarios.

Important Concepts to Master:

  • P(E) = Number of favourable outcomes / Total outcomes
  • P(E) + P(Ē) = 1
  • Problems based on playing cards, dice, marbles, and coloured balls
  • Understanding impossible and certain events

Myclass24 Tip: Learn the complete structure of a standard deck of 52 cards. Almost every board exam includes at least one card-based probability problem.
