The angle AOB and the ray OC, OM and on are known to divide the angle AOC and the angle BOC equally. (1) if OC is outside the angle AOB, the relationship between the angle mon and the angle AOB is studied. If OC is outside the angle AOB, then: ∠ MOC = (1 / 2) (∠ AOB + ∠ BOC) = (1 / 2) ∠ AOB + (1 / 2) ∠ BOC ∠ NOC = (1 / 2) ∠ BOC, so, ∠ mon = ∠ MOC - ∠ NOC = (1 / 2)}
