Question

to verify that angle opposite to equal rides of a triangle are equal​

Answer 1

ANSWER:------------

{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 equal.

Hence proved
