Front Row: David Hankin- AIME Chair, Kiran Kedlaya, Dick Gibbs, Cecil Rousseau, Richard Stong. USAMO Grading, Solution 1. Connect segment PO, and name the interaction of PO and the circle as point M. Since PB and PD are tangent to the circle, it's easy to see that M is the midpoint of arc BD. ∠ BOA = 1/2 arc AB + 1/2 arc CE. Since AC // DE, arc AD = arc CE, thus, ∠ BOA = 1/2 arc AB + 1/2 arc AD = 1/2 arc BD = arc BM = ∠ BOM.
