🔆 Pythagoras Theorem Controversy: India vs Greece Origins?
📍 What’s in the News?
✅ A Karnataka Govt position paper under NEP 2020 described Pythagoras’s theorem as “fake news”, claiming Baudhayana Sulbasutra already stated it.
📍 Who was Pythagoras?
✅ A Greek philosopher (c. 570–490 BCE)
✅ Known more through his followers; no direct writings survive
✅ Founded a secretive school in Italy
✅ Contributions are hard to attribute directly to him
📍 What is the Pythagoras Theorem?
✅ Applies to right-angled triangles
✅ Formula: a² + b² = c² (where ‘c’ is hypotenuse)
✅ If any 2 sides are known, the third can be calculated
📍 India’s Ancient Knowledge – Baudhayana Sulbasutra
✅ Dated to around 800 BCE (older than Pythagoras)
✅ Vedic text on altar construction for yajnas
✅ States the Pythagorean relation as a geometric truth (not a theorem)
✅ Used in designing vedis (altars) in isosceles triangles, trapezia, rectangles
✅ Considered one of the earliest geometric texts in India
📍 Global Evolution of the Theorem
✅ Babylonian civilisation (1900–1600 BCE) referred to it as Diagonal Rule
✅ Euclid’s Elements (~300 BCE) has the first axiomatic proof
📍 Conclusion
✅ While Pythagoras popularized it in Greece, evidence suggests Indians, Babylonians, and others knew it much earlier
✅ The term “fake news” is controversial — but ancient Indian texts like Sulbasutras did state the concept well before Greek formalization
