A circle is the set of all points that are the same distance from one given point. Find an example that contradicts this definition, How would you change the definition to make it more accurate?

Give an example of an undefined term and how it relates to a circle

If contradicts, so it should be the sphere.

The example of an undefined term should be the point, line, etc

Since the circle is the set of all kinds of similar distances from one point so here the contradicts should be that

Now the accurate definition is

The undefined term example should be

It is set to all kinds of points in the 2-dimensional figure from a circle and the same should be located at the similar distance from a given point so it is known as the center at the circle.
