"To summarise, there were different ways to measure angles very accurately in Indian tradition. An angle was defined in the sophisticated way as the length of a curved line, not in the naïve way as something (what thing?) made by two straight lines meeting at a point. The reference to 360 and 720 as a way to measure revolutions is indeed found in the Rgveda, and relates to astronomy and the calendar. Texts like Vedanga Jyotisa (– 1500 CE) use more accurate measures of angles in fractions of degrees. Similar accuracy in angle measurement was part of navigational and astronomical practice."
