In 2007, the answer to the 25th question of mathematics in the senior high school entrance examination in Kaifeng.
> as shown in the figure, when point e coincides with point m, the arc AM(E) = 67.25 > the corresponding circumferential angle ∠ abm; ∠ AEB = 45。 When point e moves along the fillet to point b, arc AE >；; Arc AM, so there is ∠ Abe > ∠ABM & gt； ∠AEB, so there is AE & gtAB.
