a) Xét Δ OAD và Δ OBD có:
góc AOD = góc BOD (gt)
AD: cạnh chung
OA = OB (GT)
=>Δ OAD = Δ OBD (c.g.c)
=> DA = DB (2 cạnh tương ứng) (đpcm)
b/ Ta có: Δ OAD =Δ OBD (câu a)
=> góc ODA = góc ODB (2 góc tương ứng)
Mà góc ODA + góc ODB = 1800 (kề bù)
=> góc ODA = góc ODB = 1800 / 2 = 900
Vậy OD ⊥ AB (đpcm)
