AS = 6 सेमी
BC = 12 सेमी
CR = 5 सेमी
प्रयुक्त अवधारणा:
यदि एक बाह्य बिंदु से एक वृत्त पर दो स्पर्श रेखाएँ खींची जाती हैं तो उनके स्पर्शरेखा खंड समान होते हैं।
गणना:
⇒ CR = CQ = 5 सेमी
⇒ BQ = BC – CQ
⇒ (12 – 5) = 7 सेमी
⇒ BQ = BP = 7 सेमी ....(1)
⇒ AS = AP = 6 सेमी ....(2)
समीकरण (1) और (2) को जोड़ने पर, हम प्राप्त करते हैं
⇒ (7 + 6)
⇒ 13 सेमी
इसलिए, AB की लंबाई 13 सेमी है
