Sulbha Sutras – Geometry in Ancient India (Part 2)

Vedic scholars documented the value of √2 with 4th decimal accuracy in 800 BC – that means they knew this few 100 years before that orally. They also knew Pythagorean theorem before Pythagoras. They listed many Pythagorean triplets and gave a general rule for generating many more. They knew the value of π. They were familiar with recursion, infinite series and irrational numbers.

In this 2nd part of 2 part series on geometry in ancient India, we will go through few “Sulbha Sutras” like finding east, pythagoream theorem, pythagorean triplets, adding squares, substracting squares, converting square into a circle and more..
