For in the \*Śulbasūtra\*, the area is technically called \*bhūmi\*, not \*kṣetra\* which denotes “figures.” These prove conclusively that the universal geometrical character of the theorem was fully recognised. - [Previous: c14.27](https://indike.org/pramana/ins.science.datta-1932.c14.27) - [Next: c14.29](https://indike.org/pramana/ins.science.datta-1932.c14.29) - [Up: c14](https://indike.org/pramana/ins.science.datta-1932.c14) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c14.28](https://indike.org/pramana/ins.science.datta-1932.c14.28) · Pramāṇa
