Open this script to get the construction of the circle.

Here are some of the answers to your investigation:

• The point D is equidistant from the rays AP, AQ, and the segment BC because the points lying on an angle bisector are equidistant from the sides of the angle.
• The circle with center point D and radius the distance from D to the side BC is called Externally Tangent Circle .
