With centre \*B\* and radius \*BC\* describe a circle. Similarly with centre \*C\* and radius \*CB\* describe another circle. Let \*D\* and \*E\* be the points of intersection of these two circles. Join \*AD\* or \*AE\* or \*DE\*. Then this straight line will be at right angles to the given straight line \*BC\* at \*A\*. - [Previous: c10.12](https://indike.org/pramana/ins.science.datta-1932.c10.12) - [Next: c10.14](https://indike.org/pramana/ins.science.datta-1932.c10.14) - [Up: c10](https://indike.org/pramana/ins.science.datta-1932.c10) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c10.13](https://indike.org/pramana/ins.science.datta-1932.c10.13) · Pramāṇa
