Question

question 1 of 10 which of these is the best definition of a circle? a. the set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant b. the set of all points in a plane for which the difference between the distances to two fixed points equals a certain constant c. the set of all points in a plane that are a certain distance from a single point d. the set of all points in a plane that are equidistant from a single point and a line

Explanation:

A circle is defined as the set of all points in a plane that are at a fixed - distance (radius) from a single point (center). Option A describes an ellipse, option B describes a hyperbola, and option D describes a parabola.

Answer:

C. The set of all points in a plane that are a certain distance from a single point
