Answer and Step-by-step explanation:
A line is the set of all points that are equidistant from two points.
Because line is the set of line which two points and it can be extended from both the sides.
So, there are no end points.
A Circle is the set of all points that are equidistant from a given point. The given point is called the centre . The segment showing the distance is called the radius.
Circle is the set of points equidistant from the centre and distance between centre and any point on circumference of circle is known as radius.
A parabola is the set of all points equidistant from a single point and a single line. The single point is called the focus and the single line is called the directrix.
Parabola is equidistant from focus and directrix.
