let the circle touch one line at A and the other at B.
then if O is the center of the circle,
then OA and OB have to be perpendicular to the respective lines.
since OA and OB are the radii of the same circle,
O is equidistant from the lines
thus, using the definition of angle bisector that i'ts a set of points equidistant from the arms of the angle,
we conclude that O lies on the angle bisector of the angle between the two intersecting lines.
