Pythagorean Theorem
In this Class 10 Mathematics topic from the chapter Triangles, students learn the Pythagorean Theorem for right-angled triangles: the square of the hypotenuse equals the sum of the squares of the other two sides, written as c² = a² + b². They practise identifying the hypotenuse, finding unknown side lengths, checking whether a triangle is right-angled using the converse theorem, and applying the relationship to geometric diagrams and everyday measurement problems.
