1, solution: ∠ BOD = ∠ AOC = 120 (equal vertex angles),

∠ AOD = 180-∠ AOC = 60 (adjacent complementary angle definition),

∫OE segmentation ∠AOD,

∴∠AOE= 1/2∠AOD=30 .

2、∵∠2=∠3,∠ 1=∠2,

∴∠ 1=∠3,

∴BD∥CE (same angle, two straight lines are parallel),

∴∠D=∠FEC (two straight lines are parallel and have the same included angle),

∠∠C =∠D，

∴∠C=∠FEC，

∴DF∥AC (internal dislocation angles are equal and two straight lines are parallel),

∴∠∠
