Which geometric object is defined as the set of all points in a plane that are equidistanct from the two sides of a given angle?

The geometric object defined as the set of all points in a plane that are equidistant from the two sides of a given angle is known as the angle bisector. It is a straight line that divides the angle into two equal angles and extends infinitely in both directions. Every point on the angle bisector is equidistant from the two sides of the angle.
