अपनी अभ्यास पुस्तिका पर एक \( \angle PQR =60^{\circ} \) तथा दूसरा कोण \( \angle ABC =45^{\circ} \) खींचिए। \( \angle PQR \) में एक ऐसी रेखा \( QN \) खींचिए जिससे \( \angle PQN =\angle PQR -\angle ABC \) हो जाएँ तथा \( \angle PQN \) का मान बताइये।

ज्ञात है – बड़ा ∠PQR तथा छोटा कोण ∠ ABC

रचना करनी है – ∠PQN = ∠PQR – ∠ ABC के बराबर कोण की

रचना – सर्वप्रथम अज्ञात नाप का एक बड़ा ∠PQR तथा एक छोटा ∠ABC खींचिए। अब ∠ABC के बराबर रेखाखण्ड QR पर ∠NQR बनाइए।

अतः ∠NQR = ∠ABC

∠PQN = ∠PQR – ∠NQR

∠PQN =∠PQR – ∠ABC

\(\therefore\) ∠PQN = 15°
