The intersection of a plane and a right circular cone.
The line segment related to a hyperbola of length 2b whose midpoint is the center.
A conic which is not a parabola, ellipse, circle, or hyperbola. These include lines, intersecting lines, and points.
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.
The ratio in an ellipse or hyperbola. Under the polar definition of conics, e is the constant ratio of the distance from a point to the focus and the distance from that point to the directrix.
The set of all points such that the sum of the distances from the point to each of two fixed points is constant.
The set of all points such that the difference of the distances between each of two fixed points and any point on the conic is constant.
The line segment containing the foci of an ellipse whose endpoints are the vertices whose length is 2a.
The line segment containing the center of an ellipse perpendicular to the major axis whose length is 2b.
The line segment that contains the center and whose endpoints are the two vertices of a hyperbola.
