c# - Intersecting points of curve! -

i drawing arc within square or polygon maximum possible radius inside. when arc drawn within boundary of square or polygon, arc length intersect @ few points on square or polygon.

how find coordinates of intersecting points of arc @ periphery of square/ polygon?

the line segment of polygon has (or hasn't) tangent point distance center point of arc arc radius.

if problem project 2 lines parallel segment on either side of segment @ distance of radius, determine if either line intersects arc center point, if not, no tangent exists...

if so, point of intersection relative projected segment proportional tangent on original segment.
