Question

which of the following is the best definition of a circle? a. a plane figure similar to a hexagon b. the collection of all points in a plane that are the same distance from a given line c. a polygon with curved sides d. the collection of all points in a plane that are the same distance from a given point

Explanation:

A circle is defined as the set of all points in a plane that are equidistant from a fixed - point called the center. Option A is incorrect as a circle is not similar to a hexagon. Option B describes two parallel lines (the set of points equidistant from a given line). Option C is incorrect since a polygon has straight - sided figures and a circle is a curved figure. Option D correctly states the definition of a circle.

Answer:

D. The collection of all points in a plane that are the same distance from a given point
