Class 8 Maths - CBSE
The Baudhayana-Pythagoras Theorem
The chapter on the Baudhayana-Pythagoras Theorem for Class 8 CBSE students introduces one of the most powerful and fundamental concepts in geometry. Students learn about the properties of right-angled triangles, specifically the relationship between the lengths of the base, perpendicular, and hypotenuse. The chapter explores the historical contribution of the ancient Indian mathematician Baudhayana alongside Pythagoras. Mastering this chapter is essential for board exams as it forms the bedrock for advanced geometry, trigonometry, and coordinate geometry in higher classes, frequently appearing in both direct calculation problems and multi-step word problems.

Right-Angled Triangle
A triangle in which one angle is exactly 90 degrees, serving as the base figure for applying the theorem.
Hypotenuse
The longest side of a right-angled triangle, which is always located directly opposite to the 90-degree right angle.
Baudhayana-Pythagoras Theorem
The mathematical rule stating that in any right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Pythagorean Triplets
A set of three positive integers (a, b, c) that satisfy the condition a squared plus b squared equals c squared.
Important Formulas
Board Exam Info
In CBSE Class 8 mathematics exams, this chapter typically carries around 5 to 8 marks. Common question types include finding the missing side of a right-angled triangle, verifying whether a given set of numbers forms a Pythagorean triplet, and solving practical word problems involving ladders, trees, or distances.
Frequently Asked Questions
Why is it called the Baudhayana-Pythagoras Theorem instead of just the Pythagoras Theorem?
Indian mathematician Baudhayana stated this geometry rule in the Sulba Sutras centuries before Pythagoras, which is why the CBSE curriculum recognizes both.
How do I identify which side is the hypotenuse?
The hypotenuse is always the longest side and sits directly across from the 90-degree right angle in the triangle.
Can we apply this theorem to any triangle?
No, this theorem only works for right-angled triangles where one interior angle measures exactly 90 degrees.
