Class 8 Maths - PUNJAB
The Baudhayana-Pythagoras Theorem
The chapter 'The Baudhayana-Pythagoras Theorem' in Class 8 Punjab (PSEB) Mathematics introduces students to one of the most famous geometric relationships in mathematics. Students will learn about right-angled triangles, identifying the hypotenuse, base, and perpendicular. The chapter highlights the historical contribution of the ancient Indian mathematician Baudhayana, who stated the theorem long before Pythagoras. Learners will understand how to calculate the missing side of a right-angled triangle and apply this fundamental theorem to solve various numerical problems, laying a strong foundation for geometry in higher classes and board examinations.

Right-Angled Triangle
A triangle in which one of the interior angles measures exactly 90 degrees.
Hypotenuse
The longest side of a right-angled triangle, located directly opposite to the 90-degree right angle.
Baudhayana-Pythagoras Theorem
In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Pythagorean Triplet
A set of three positive integers (a, b, c) that satisfy the condition where a squared plus b squared equals c squared.

Common question types include finding the length of the unknown side of a right-angled triangle when two sides are given, verifying whether given side lengths form a right-angled triangle, and word problems based on real-life distances.
Frequently Asked Questions
Who was Baudhayana and why is his name attached to the theorem?
Baudhayana was an ancient Indian mathematician who stated this geometric rule in his 'Baudhayana Sulba Sutra' centuries before Pythagoras.
How do we find which side is the hypotenuse?
The hypotenuse is always the longest side of the right-angled triangle and it lies directly opposite the right angle (90 degrees).
Can the Pythagoras theorem be applied to all types of triangles?
No, this theorem is exclusively applicable to right-angled triangles.
