\(\Delta ABC \cong \Delta PQR\)
BC = 6 सेमी
\(\angle A = {75^o}\)
प्रयुक्त अवधारणा:
दो त्रिभुजों को सर्वांगसम कहा जाता है यदि तीनों संगत भुजाएँ समान होती हैं और तीनों संगत कोण माप में समान होते हैं।
गणना:
यदि त्रिभुज ABC और PQR सर्वांगसम हैं, तो
∠A = ∠Q और ∠B = ∠R
Δ PQR की भुजा QR, Δ ABC की भुजा BC के बराबर होनी चाहिए ताकि दोनों त्रिभुज सर्वांगसम हो जाएँ।
\(QR = 6cm,\angle P = {75^o}\)
अतः, सही उत्तर विकल्प (3) है।
