The locus of a moving point so that it is equidistant from another fixed point (i.e. the distance between them is always constant) is a circle.
A circle is the locus of a point which moves such that its distance from a fixed point is constant. .The fixed point is centre and fixed distance is radius of circle. Elements of circle are centre, radius and circumference.
It is the locus of all points such that their distance from a fixed line (the directrix) is the same as their distance from a fixed point which is not on that line (the focus).
true
A half of a hyperbola is defined as the locus of points such that the distance of the point from one fixed point (a focus) and its distance from a fixed line (the directrix) is a constant that is greater than 1 (the eccentricity). By symmetry, a hyperbola has two foci and two directrices.

Locus
It is going to look like a somewhat of a quadratic parabola.
True
I assume that you are asking about the definition of a circle. A circle is a locus of points in a plane that are at a constant distance from a fixed point.

It is the locus of a point such that the sum of its distance from two (distinct) fixed points is a constant. So, given two fixed points, F1 and F2, an ellipse is the locus of the point P such that PF1 + PF2 is a constant. That would be an ellipsoid, a 3 dimensional thing. The 2 distances have to be measured in a fixed (2 dimensional) plane.
