সঠিক উত্তর: । ব্যাখ্যা: যদি $\angle ABC = 100^\circ$ এবং $AB = BC$ হয়, সেক্ষেত্রে $\triangle ABC$ একটি সমদ্বিবাহু ত্রিভুজ। $\angle BAC = \angle BCA = \frac{180^\circ - 100^\circ}{2} = \frac{80^\circ}{2} = 40^\circ$.

\(ABC\) is a triangle where the angle \(\angle ABC = 100^\circ\) and \(AB = BC\), find the measure of the angle \(\angle BAC\).
