Download Solution PDFदिया गया है:
∠BAC = ∠BCD, AB = 32 सेमी और BD = 18 सेमी
संकल्पना:
यदि दो त्रिभुज समरूप हैं, तो संबंधित भुजाओं का अनुपात समान होगा।
गणना:
त्रिभुज ABC और CBD में;
∠BAC = ∠BCD
∠B उभयनिष्ठ है
अतः, त्रिभुज ABC और CBD कोण-कोण समरूपता द्वारा समरूप हैं।
∴ AB/CB = BC/BD
⇒ BC2 = 32 × 18 = 576
∴ BC 24 सेमी है
