Part A: 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? Part B: Give an example of an undefined term and how it relates to a circle.

Explanation:

Part A:  Let's say we have a figure having a set of points, but the set of all points on this figure are not on a plane (flat surface), it means they cannot be of the same distance from a fixed point because as this set of points aren't on a plane there would be irregularities in their distances from the fixed point.

A more proper definition could be: A circle is the set of all points on a plane that has the same distance from one fixed point.

Part B: A good example is the term radius (radius of a circle), which refers to any line or interval that joins or touches a point on the circle to the center.

Part B- A point is a undefined term that relates to the circle because the point is the center of the circle
