Axis : The line over which a parabola is symmetric.
Branch : The term for each of the two distinct sections of the graph of a hyperbola.
Center : For an ellipse and hyperbola, the midpoint between the foci. For a circle, the fixed point from which all points on the circle are equidistant.
Circle : The set of all points equidistant from a given fixed point.
Conic : The intersection of a plane and a right circular cone.
Degenerate Conic : A conic which is not a parabola, ellipse, circle, or hyperbola. These include lines, intersecting lines, and points.
Directrix : For a parabola, it is the line whose distance from any point on the parabola is the same as the distance from that point to the focus.
Ellipse : The set of all points such that the sum of the distances from the point to each of two fixed points is constant.
Focus : For a parabola, the point whose distance from any point on the parabola is the same as the distance between that point and the directrix. For an ellipse, one of two points--the sum of whose distances to a point on the ellipse is constant. For a hyperbola, one of two points--the difference of whose distances to a point on the hyperbola is constant.
Hyperbola : The set of all points such that the difference of the distances between each of two fixed points and any point on the curve is constant.
Parabola : The set of all points such that the distance between a generic point and a fixed line is the same as the distance between a generic point and a fixed point.
Radius : A segment between the center of a circle and a point on the circle, or sometimes, the length of that segment
Vertex :For a parabola is the point halfway between the focus and the directrix.
