A circle or a sphere
circle
A circle or a sphere would fit the given description.
The apothem is the distance from the center to the middle of any side on a regular polygon. That is, a shape with every single side and angle the same.

A circle is the set of all the points that are the same (arbitrary) distance (called the radius) from some (arbitrary) point (called the center).
A sphere.
If the shape is two-dimensional then it is a circle, if the shape is three-dimensional then it's a sphere.
A circle or a sphere could fit the given description
The shape of a circle is round. Circles are plane shapes that have all points that are the same distance from the center.
A circle has all of it's points the same distance from the center. For example, if you put a dot on a given point on the circumference, or outline of a circle, all the points have the same distance from the circle. This only works if you put a point on the outline or circumference of the circle.
circle, square, equilateral triangle, rhombus, etc.
A collection of points in a plane that are the same distance from a center point forms a circle. The center point is known as the center of the circle, and the constant distance from this center to any point on the circle is called the radius. All points on the circle maintain this uniform distance from the center, creating a perfectly round shape.
A curved surface on which all points are the same distance from the center is called a sphere.
A circle is the set of all the points that have the same distance from a given point (its center). If you rotate a shape, you rotate it in such a way that you keep any point a fixed distance from the center of rotation.
In 2 dimensions, it's a circle. In 3 dimensions, it's a sphere.
A circle is a set of points equidistant ( the same distance ) away from a single point, the center of the circle.
if it's a circle, all points are equidistant from the center.
