Class 8 Maths - HARYANA
The Baudhayana-Pythagoras Theorem
The Baudhayana-Pythagoras Theorem chapter in Class 8 Mathematics for Haryana (BSEH) students introduces one of the most famous geometric relationships in mathematics. Students learn about right-angled triangles and the profound contribution of the ancient Indian mathematician Baudhayana, who stated this rule centuries before Pythagoras. The chapter covers the relationship between the hypotenuse, base, and perpendicular of a right-angled triangle. Mastering this chapter is essential for scoring well in BSEH board exams as it forms the foundational basis for advanced geometry, trigonometry, and coordinate geometry in higher classes.

Right-Angled Triangle
A triangle in which one angle measures exactly 90 degrees.
Hypotenuse
The longest side of a right-angled triangle, which is located directly opposite to the 90-degree angle.
Baudhayana-Pythagoras Theorem Statement
In a 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.

Frequently Asked Questions
Who was Baudhayana and what is his contribution?
Baudhayana was an ancient Indian mathematician who stated the geometric rule relating the sides of a right triangle in the Sulba Sutras long before Pythagoras.
How do I know which side is the hypotenuse?
The hypotenuse is always the longest side of the right-angled triangle and is always positioned directly opposite the right angle.
Can the theorem be applied to all types of triangles?
No, the Baudhayana-Pythagoras theorem is exclusively applicable only to right-angled triangles.
