यदि रेखाओं
a1 ⋅ a2 + b1 ⋅ b2 + c1 ⋅ c2 = 0
गणना:
दिया हुआ: दो रेखाओं का समीकरण है
दिए गए समीकरण को फिर से इसप्रकार लिखा जा सकता है:
दी गई रेखाओं के दिशा अनुपात हैं:
⇒ a1 = - 3, b1 = 2k/7, c1 = 2, a2 = - 3k/7, b2 = - 1 और c2 = - 5
∵ दी गई रेखाएं एक-दूसरे के लिए लंबवत हैं
जैसा कि हम जानते हैं कि यदि दो रेखाएं एक-दूसरे के लिए लंबवत हैं then a1 ⋅ a2 + b1 ⋅ b2 + c1 ⋅ c2 = 0
⇒
⇒ k = 10
