    Shortcut Trick\n

    यदि किसी त्रिभुज के कोण समांतर श्रेणी (Arithmetic Progression) में हैं (अर्थात, एक कोण अन्य दो का औसत है), तो बीच का कोण हमेशा π/3 (या 60°) होता है।

    \n

    दिए गए विकल्पों की जाँच करने पर, केवल पहले सेट में π/3 है और इसका योग π रेडियन है।

    \n

    योग = π/6 + π/3 + π/2 = π.

    \n

    π/6 और π/2 का औसत = (π/6 + π/2) ÷ 2 = (4π/6) ÷ 2 = π/3.

    \n

    ∴ सही उत्तर π/6, π/3, π/2 है।

    \n\n

    Alternate Method

    \n

    दिया गया है:

    \n

    त्रिभुज का एक कोण अन्य दो कोणों का अंकगणितीय औसत है।

    \n

    प्रयुक्त सूत्र:

    \n

    एक त्रिभुज के आंतरिक कोणों का योग = π रेडियन।

    \n

    औसत = (मानों का योग) ÷ मानों की संख्या

    \n\n \n \n \n \n A\n B\n C\n π/6\n π/3\n π/2\n समांतर श्रेणी में कोणों वाला समकोण त्रिभुज\n\n

    गणना:

    \n

    ⇒ माना त्रिभुज के तीन कोण A, B, और C हैं।

    \n

    ⇒ दी गई शर्त के अनुसार, माना B, A और C का औसत है: B = (A + C) ÷ 2

    \n

    ⇒ 2 से गुणा करने पर, हमें प्राप्त होता है: 2B = A + C

    \n

    ⇒ हम जानते हैं त्रिभुजों का योग गुण: A + B + C = π

    \n

    ⇒ योग समीकरण में A + C = 2B प्रतिस्थापित करने पर:

    \n

    ⇒ B + (A + C) = π

    \n

    ⇒ B + 2B = π

    \n

    ⇒ 3B = π → B = π/3

    \n

    ⇒ चूँकि B = π/3, शेष योग A + C = π − π/3 = 2π/3 है

    \n

    ⇒ विकल्पों में से कोणों के पहले सेट की जाँच करने पर: π/6, π/3, π/2

    \n

    ⇒ यहाँ, बीच का कोण π/3 है। अन्य दो कोणों का योग = π/6 + π/2 = π/6 + 3π/6 = 4π/6 = 2π/3.

    \n

    ⇒ पहला सेट हमारी सभी व्युत्पन्न ज्यामितीय शर्तों से पूरी तरह मेल खाता है।

    \n

    ∴ सही उत्तर π/6, π/3, π/2 है।

    Additional Information

    \n

    कोणों की समांतर श्रेणी (Arithmetic Progression)

    \n

    जब किसी त्रिभुज के कोण समांतर श्रेणी (A.P.) में होते हैं, तो बीच का कोण हमेशा बिल्कुल 60° (या π/3 रेडियन) होता है, चाहे अन्य दो आसन्न कोण कुछ भी हों।

    \n

    कोणों के योग का गुण

    \n

    किसी भी यूक्लिडियन समतलीय त्रिभुज के आंतरिक कोणों का योग सख्ती से 180° के बराबर होता है (जो बीजगणितीय रूप से π रेडियन के बराबर है)। सार्वभौमिक सूत्र: A + B + C = π.

Finally, (A) explains a specific function of \"these\" (the telescopes mentioned in D), completing the logical flow from the general definition to specific equipment and its function.
