    yes they are equal

    Theorem : Angles opposite to equal sides of an isosceles triangle are equal.

    Proof :

    We are given an isosceles triangle ABC in which AB = AC. We need to prove that ∠B = ∠C.

    Let us draw the bisector of ∠ A and let D be the point of intersection of this bisector of ∠ A and BC.

    In Δ BAD and Δ CAD,

    AB = AC (Given)

    ∠BAD = ∠CAD (By construction)

    AD = AD (Common)

    So, Δ BAD ≅ Δ CAD (By SAS rule)

    So, ∠ABD = ∠ACD, since they are corresponding angles of congruent triangles.

    So, ∠B = ∠C
