Question

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

∠ABC ≅ ∠ABD
∠ABD ≅ ∠CBE
∠CBD ≅ ∠DBE
∠CBD ≅ ∠ABC

Answer 1

∠ABC ≅ ∠ABD

Explanation:

By reflexive, A and A are congruent and B and B are congruent.

Then, since those angles are congruent, the last ones (C and D) must be congruent to each other.
