CHAPTER AT A GLANCE
The Baudhāyana-Pythagoras Theorem
•Unit: Geometry
•Board weightage: The Baudhāyana-Pythagoras theorem, finding missing sides, Pythagorean triples and square roots of non-square numbers give regular 2-mark, 3-mark and 4-mark questions (please check the latest sample paper)
•Key ideas from the textbook: the area proof of the theorem, the hypotenuse of an isosceles right triangle, the number √2, Pythagorean triples, converse of the theorem, applications in rhombus, rectangle and square, Śulba-Sūtra of Baudhāyana
•Most scoring part: writing the theorem, substituting into a² + b² = c², simplifying and writing the final line with the unit
•Time to revise: about 60 minutes
