Given that ∠ABC ≅ ∠DBE, which statement must be true?∠ABC ≅ ∠ABD∠ABD ≅ ∠CBE∠CBD ≅ ∠DBE∠CBD ≅ ∠ABC

Answer ∠ABD ≅ ∠CBE   is correct statement It is given that ∠ABC ≅ ∠DBE, Here vertex B is common for two triangles.It implies that, ∠ABCand ∠DBE are pair of vertically opposite angles. (vertically opposite angles are equal. ∠ABC ≅ ∠ABD False. (Ab is common, These angles are adjacent s angles) ∠ABD ≅ ∠CBE  True.(B is the common vertex, another pair of vertically opposite angle)) ∠CBD ≅ ∠DBE Fasle  ∠CBD ≅ ∠ABC False
