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.
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.

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 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.
Parabola - apex
They are parallel lines
The bisector of that angle.
