Class 8 Maths - GUJARAT
The Baudhayana-Pythagoras Theorem
In this chapter, Class 8 students under the Gujarat Secondary and Higher Secondary Education Board (GSEB) explore the famous Baudhayana-Pythagoras Theorem. Long before Pythagoras, the ancient Indian mathematician Baudhayana stated this geometric rule in the Sulba Sutras. Students will learn the fundamental relationship between the sides of a right-angled theorem, specifically how the square of the hypotenuse equals the sum of the squares of the other two sides. Mastering this chapter is crucial for board exam success as it forms the foundation for advanced geometry, trigonometry, and coordinate geometry in higher classes, frequently appearing in both MCQ and descriptive problem sections.

Right-Angled Triangle
A triangle in which one angle measures exactly 90 degrees, serving as the basis for applying the Pythagoras theorem.
Hypotenuse
The longest side of a right-angled triangle, located directly opposite to the 90-degree right angle.
Baudhayana's Contribution
The ancient Indian sage Baudhayana stated the geometric theorem in his text Sulba Sutras centuries before Pythagoras.
Pythagoras Theorem Statement
In a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Pythagorean Triples
A set of three positive integers a, b, and c that satisfy the equation a squared plus b squared equals c squared.

Board Exam Info
In the Gujarat (GSEB) Class 8 Mathematics board-pattern exams, this chapter typically carries around 5 to 8 marks. Questions usually include multiple-choice questions (MCQs), fill-in-the-blanks, and 2 to 3-mark numerical problems where students must find the missing side of a right-angled triangle.
Frequently Asked Questions
Who discovered the theorem first, Baudhayana or Pythagoras?
Baudhayana stated this geometric principle centuries before Pythagoras in his ancient Indian mathematical text called the Sulba Sutras.
Can we apply the Pythagoras theorem to any type of triangle?
No, this theorem is exclusively applicable to right-angled triangles that have one 90-degree angle.
How do I identify which side is the hypotenuse?
The hypotenuse is always the longest side of the right-angled triangle and it is always positioned directly opposite to the right angle.
