Answer» Correct Answer - Option 2 : Circle
The correct answer is Circle. - A collection of points in a plane that are at a constant distance from a fixed point is called a Circle.
- Ellipse:-
- It may be defined as the path of a point moving in a plane so that the ratio of its distances from a fixed point (the focus) and a fixed straight line (the directrix) is a constant less than one.
- Parabola:-
- It is a curve where any point is at an equal distance from a fixed point (the focus), and a fixed straight line (the directrix ).
- Hyperbola:-
- It is a plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant: a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.
