Red Line  Testing a line inside a circle, but has no intersect 5.) Green Line  Testing line starting inside a circle that intersects circle at one point. 6.) Orange Line  A line starting/ending outside circle that intersects circle at two points 7.) Maroon Line  A line from the center circle to a point within the circle: Extend line to its circle intersect point.
