Frequently Asked Questions
Who was Baudhayana and what was his contribution?
Baudhayana was an ancient Indian mathematician who stated the geometric rule relating the sides of a right triangle in his Sulba Sutra, centuries before Pythagoras.
How do I identify which side is the hypotenuse?
The hypotenuse is always the side opposite to the 90-degree right angle, and it is also the longest side of the right-angled triangle.
Can the theorem be applied to all types of triangles?
No, the Baudhayana-Pythagoras theorem is exclusively applicable only to right-angled triangles.
