ACBAC = ∠ বিবিসিডি, এবি = 32 সেমি এবং বিডি = 18 সেমি
চুক্তি:
দুটি ত্রিভুজ যদি সমান হয় তবে সংশ্লিষ্ট পক্ষের অনুপাত সমান হবে।
গণনা:
ত্রিভুজ এবিসি এবং সিবিডি;
ACBAC = ∠ বিবিসিডি
∠ বি সাধারণ
অতএব, ত্রিভুজগুলি এবিসি এবং সিবিডি এএ মিলের দ্বারা মিল রয়েছে।
∴ এবি / সিবি = বিসি / বিডি
⇒ বিসি 2 = 32 × 18 = 576
⇒ বিসি = 24 সেমি
