A circumcircle is a circle which passes through all vertices of a triangle and an incircle is a circle which is inscribed in a triangle touching all sides of a triangle. Let ABC be a right-angled triangle whose radius of the circumcircle is 5 and its one side AB = 6. The radius of incircle of triangle ABC is r. Area of Delta ABC is

length OF angle bisector (length OF medians)

ABCD is a quadrilateral inscribed in a circle (radius=r). The bisectors of the angles DAB and BCD intersect the circle at X and Y. respectively. What is the length of the straight line XY?
