Class 8 Maths - RAJASTHAN
The Baudhayana-Pythagoras Theorem
In this chapter, Rajasthan Board Class 8 students will explore the famous Baudhayana-Pythagoras Theorem, a fundamental geometric principle that relates the sides of a right-angled triangle. Long before Pythagoras, the ancient Indian mathematician Baudhayana stated this relationship in his Sulba Sutras. You will learn how to identify the hypotenuse, base, and perpendicular of a right triangle and use the theorem to find missing side lengths. This chapter is very important for board exams as it forms the basis of advanced geometry, trigonometry, and coordinate geometry in higher classes, making it a high-scoring topic.

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, which is located directly opposite to the 90-degree right angle.
Baudhayana-Pythagoras Theorem
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 Triplets
A set of three positive integers a, b, and c that satisfy the condition where a squared plus b squared equals c squared.

Board Exam Info
In the Rajasthan Board Class 8 Mathematics examination, this chapter typically carries around 4 to 6 marks. Common question types include finding the unknown length of a triangle's side, verifying if given side lengths form a right-angled triangle, and word-based practical problems.
Frequently Asked Questions
Who was Baudhayana and what is his contribution?
Baudhayana was an ancient Indian mathematician who stated the geometric rule for right-angled triangles in the Baudhayana Sulba Sutra centuries before Pythagoras.
How do I know which side is the hypotenuse?
The hypotenuse is always the longest side of the right-angled triangle and it is always directly opposite to the right angle (90 degrees).
Can the theorem be applied to all types of triangles?
No, the Baudhayana-Pythagoras Theorem is applicable exclusively to right-angled triangles.
