Question

what is the measure of the angle between the internal and exterior bisector of an angle

Answer 1

It is always 90 degree.

Example. An equilateral triangle has its interior angle as 60 degree and its exterior angle as 120 degree. So the angle between the bisectors of the exterior and interior angles is 60/2 + 120/2 = 30 + 60 = 90 degree
