Bhaskara's theorem

Bhaskara's theorem, attributed to the Indian mathematician Bhaskara II in the 12th century, states that for any given triangle, the area can be calculated using its side lengths without needing the height. Specifically, if you know the lengths of all three sides, you can compute the area using Heron's formula, which involves the semi-perimeter of the triangle. This theorem highlights a significant advancement in mathematical understanding, demonstrating how geometry can be connected to algebra, and it has practical implications in fields like architecture and engineering where calculating areas is essential.
