The construction below shows the bisection of ∠A.

Which of the following can be used to prove that ⊿ABD is congruent to ⊿ACD by the SAS triangle congruence theorem? Select all that apply.

• A. ∠BAD ≅ ∠ACB

• B. ∠BAD ≅ ∠CAD

• m∠BDA = m∠CDA = 90°

• segment AD ≅ segment AD

• segment AB ≅ segment AC

Find x, then the measure of AD
