It could be a circle or a sphere
A circle (2D) or a sphere (3D)
If your asking "What is ...?" Then, the answer is a circle. This is the definition of a circle!
line
A line.
A geometric shape that can be described as a fixed distance along a line is a circle. Specifically, a circle is defined as the set of all points in a plane that are equidistant from a central point, known as the center. The fixed distance from the center to any point on the circle is called the radius.

A geometric shape that can be described as a fixed distance along a line is a circle. Specifically, a circle is defined as the set of all points in a plane that are equidistant from a central point, known as the center. The fixed distance from the center to any point on the circle is called the radius.
The figure you are describing is a sphere. In a sphere, every point on its surface is equidistant from a central point, known as the center of the sphere. This constant distance from the center is referred to as the radius. Spheres are three-dimensional shapes and can be found in various contexts, such as in geometric studies and in nature.
It depends on how many dimensions you are asking about. If you are talking about a 2-dimensional figure then it would be a circle. The definition of a circle is the collection of points that are equidistant from the center. If you are talking about a 3-dimensional figure, then it would be a sphere. The definition of a sphere is the collection of points in three dimensions that are equidistant from the center.

The bisector of that angle.
