अवधारणा In a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides ($a^2 + b^2 = c^2$). This rule helps you find the shortest distance between two points.
कहानी We all know the name Pythagoras, but the secret of the right-angled triangle was actually a sacred architectural requirement in India long before he was born. Vedic architects were the ultimate perfectionists; they believed a fire altar had to be mathematically perfect for a ritual to succeed. In the Baudhayana Sulba Sutra, they recorded the rule: the diagonal of a rectangle produces an area equal to the sum of its sides. They even used ‘Pythagorean Triples’ (like 3-4-5) as a shortcut for construction. Pythagoras may have the name, but the Indian Rishis had the blueprint 4,000 years earlier.

संस्कृत श्लोक: दीर्घस्याक्ष्णया रज्जुः पार्श्वमानी तिर्यग्मानी चयत्पृथग्भूते कुरुतस्तदुभयं करोति ॥ लिप्यंतरण: Dīrghacaturasrasyākṣṇayā rajjuḥ pārśvamānī tiryaṅmānī ca yat pṛthagbhūte kurutastadubhayaṃ karoti. अर्थ: ‘The diagonal of a rectangle produces the areas which the two sides produce separately.’ (Baudhayana — Sulba Sutra -1.48)
संबंधित नवाचार The Sutras used Pythagorean triples such as (5, 12, 13) to calculate accurate angles on the ground and discovered the square root of 2 to four decimal places (1.4142) for diagonal precision.
