The perpendicualrs PQ, P₀Q₀, P₁ Q₁ and PS are drawn. From the similar triangles P₁SP and OQ₀P₀, we have P₁S = (OQ₀ · P₁P)/OP and PS = (P₀Q₀ · P₁P)/OP₀. - [Previous: c9.25](https://indike.org/pramana/ins.science.bag-1979.c9.25) - [Next: c9.27](https://indike.org/pramana/ins.science.bag-1979.c9.27) - [Up: c9](https://indike.org/pramana/ins.science.bag-1979.c9) --- Source: [https://indike.org/pramana/ins.science.bag-1979.c9.26](https://indike.org/pramana/ins.science.bag-1979.c9.26) · Pramāṇa
