NCERT Solutions for Class 10 Maths PDF Chapter 1: Real Numbers In class 9, we have studied rational numbers and irrational numbers collectively forming real numbers. Getting LCM and HCF using prime factorisation and Euclidâ€™s division lemma. Proving square roots of 2, 3, 5 are irrational numbers.

Chapter 2: Polynomials We have learnt Degree and coefficient of terms of polynomial and their factorization in class 9. Now we will find the relationship between the zeroes and their coefficient. Use of factor theorem to find the zeroes of the polynomials with degree 2, 3 or 4. Chapter 3: Pair of Linear Equations in Two Variables You have studied a linear equation in one variable and two variables in previous class. Now there is solution of pair of linear equations in class 10, using various methods like graphically, elimination, substitution and cross multiplication. Factorization, Completing the square method and using quadratic formula. Checking the nature of roots using discriminant.

Chapter 5: Arithmetic Progression To check whether the given sequence is in Arithmetic Progressions or not. To find the missing term of the AP and sum of the given sequence. To determine AP when sum to n terms is given. Some application base questions from daily life. Proof of Pythagoras theorem and its converse. Chapter 7: Coordinate Geometry Representation of points in Cartesian plane and finding the distance between two points using distance formula.

Section formula to find the ratio and mid points. Formula for area of triangle and to prove the collinearity of three points. Chapter 8: Introduction to Trigonometry Trigonometry is the oldest branch of mathematics. It is a basic introduction to class 10 about trigonometry. Using the relationship between these ratios, proving some identities.

Chapter 9: SomeÂ Applications of Trigonometry In this chapter, the techniques are used to solve problems regarding height and distances in life around us. For example, the height of hill, width of river, distance between two celestial objects cannot be measured by measure tape. So, method of trigonometric ratio is helpful in measuring such distances. Chapter 10: Circles This chapter includes the intersection of a line and circle in the same plane, tangent to a circle and tangent to a circle in the limiting case of a secant when the two end points of its corresponding chord coincide. Number of tangents from a point to a circle and tangents drawn from same external point to a circle are equal. Chapter 11: Constructions Dividing a line segment into given ratio.
