... Proposed by Gregory Galperin, Eastern Illinois University, USA O306. Let ABC be a triangle with incircle γ and circumcircle Γ. Let Ω be the circle tangent to rays AB, AC, and to Γ externally, and let A0 be the tangency point of Ω with Γ. Let the tangents from A0 to γ intersect Γ again at B 0 and C 0 ...

... 1. Place your compass point on A and stretch the compass MORE THAN half way to point B, but not beyond B. 2. With this length, swing a large arc that will go BOTH above and below AB . (If you do not wish to make one large continuous arc, you may simply place one small arc above AB and one small arc ...
