2018-06-15 · Theorem 7.2 :- Angle opposite to equal sides of an isosceles triangle are equal. Given :- Isosceles triangle ABC i.e. AB = AC To Prove :- ∠B = ∠C Construction:- Draw a bisector of ∠A intersecting BC at D. Proof:- In BAD and CAD AB = AC ∠BAD = ∠CAD AD = AD BAD ≅ CAD Thus, ∠ABD = ∠ACD ⇒ ∠B = ∠C Hence, angles opposite to equal sides are
