A line that is the angle bisector.
Bisector of an angle, is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.
Certainly false for parabolae; a parabola is the locus of points in a plane which are equidistant from a point (the focus) and a line (the directrix) in that plane. It's also false for an ellipse, which is the locus of points in a plane where the sum of the distances from two other points in that plane (the foci) is constant. AND false for a hyperbola, which is the locus of points in a plane where the absolute value of the DIFFERENCE in the distance from two points in that plane (also the foci) is constant. Alternatively, a hyperbola is the locus of points in a plane where the ratio of the distance to one of the foci and to a line (the directrix) is constant (which is larger than 1; if it's exactly equal to 1, you get a parabola instead).All of these are only slightly more complicated than circles, and in fact they, alone with circles, are called "conic sections" because they all are formed by the intersection of a plane with a right circular conical surface.
That's a circle around the center, in the plane.
That set of points forms what is known as a "circle".

a straight line ..
A Circle.
you dont
I believe that is the definition of a straight line.
Bisector of an angle, is defined as the set of all points in a plane that are equidistant from the two sides of a given angle.
A plane midway between the two given planes and parallel to them.
A line in 2D and a plane in 3D A perpendicular bisector of the line connecting the 2 given points
It's another line, parallel to both of the first two and midway between them.
The set of all points in a plane that are equidistant from the two sides of a given angle
angle bisector
The set of all points in the plane equidistant from one point in the plane is named a parabola.
All points on the circumference of a circle drawn on a plane are equidistant from the single point on the plane which is the center of the circle.
