Then having drawn a line (east-to-west) of the desired length, fix a pole at its middle. Fasten the two ties at this pole and describe a circle with the mark. Now fix poles at the both ends of the diameter (running east-to-west). Having fastened one tie at the eastern pole, describe a circle with the other tie. Describe a similar circle about the western pole. On joining the points of intersection of the circles, the second (\*i.c.\*, north-to-south) diameter will be found. Fix two poles at the extremeties of this diameter. Now, having fastened both ties at the eastern pole, describe a circle with the mark. Similarly describe circles about the southern, western and northern poles. The exterior points of intersection of these circles will determine the square.'¹ (Fig. 22.) - [Previous: c10.28](https://indike.org/pramana/ins.science.datta-1932.c10.28) - [Next: c10.30](https://indike.org/pramana/ins.science.datta-1932.c10.30) - [Up: c10](https://indike.org/pramana/ins.science.datta-1932.c10) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c10.29](https://indike.org/pramana/ins.science.datta-1932.c10.29) · Pramāṇa
