So I changed the construction a bit. Now I create a ray from P through the midpoint of AA*.

| In the last construction the angle bisector was a line. If we want the ray that lies in the angle between two rays, we need another construction. It is sometimes useful to think only of angles between 0 and 180°. |

Move B, and test what happened when
the angle APB gets larger than 180°.
