So the construction of these three altars, it will easily be recognised, pre-supposes the knowledge of the following geometrical operations:— - [Previous: c8.6](https://indike.org/pramana/ins.science.datta-1932.c8.6) - [Next: c8.8](https://indike.org/pramana/ins.science.datta-1932.c8.8) - [Up: c8](https://indike.org/pramana/ins.science.datta-1932.c8) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c8.7](https://indike.org/pramana/ins.science.datta-1932.c8.7) · Pramāṇa
