Download Solution PDFধারণা:
অষ্টভুজের আট বাহু রয়েছে।
দ্বাদশভূজের বারোটি বাহু রয়েছে।
সূত্র:
বহুভুজের অন্তঃস্থ কোণ = {(n - 2) × 180 °} / n
গণনা:
অষ্টভুজের অন্তঃস্থ কোণ = (8 – 2)/8 × 180° = 1080°/8 = 135°
দ্বাদশভূজের অন্তঃস্থ কোণ = (12 – 2)/12 × 180° = 1800°/12 = 150°
∴ অষ্টভুজ এবং দ্বাদশভুজের অন্তঃস্থ কোণের পরিমাপের অনুপাত 9 : 10
