Hi, I have some Circles and some Lines and I am trying to find their RegionIntersection. See attached notebooks for detail. The Circle is this:
oic = Circle[{0, 0}, 7.5];
The three Lines are these:
ln1 = Line[{{0, 0}, {8, 0}}];
ln2 = Rotate[ln1, Pi/9, {0, 0}];
ln3 = Line[{{0, N[7.5*Sin[Pi/9]]}, {7.5, N[7.5*Sin[Pi/9]]}}]
Line[{0, 2.56515}, {7.5, 2.56515}]
Mathematica has a hard time to find the RegionIntersection of the Circle and the rotated Line. I understand that RegionIntersection can work with just identical Heads. What I do not understand why Graphics is able to deal with the rotated Line and display it correctly but RegionIntersection is not. Any good suggestion for a workaround?
