Center It is the point (h, k) at the
center of a circle, or an ellipse, or an hyperbola

Vertex For Parabola, it is the point at
the end of the parabola For Hyperbola, it is the
turning point of a branch of a hyperbola

Focus It is the point from which
distances are measured in forming a conic
A place where the distance-lines converges

Directrix It is the line from which
distances are measured in forming a conic

Linear Eccentricity It is the distance between the
center and the focus (or one of the two foci)

Focal Parameter It is the distance between the
focus (or one of the foci) and the directrix

Locus A set of points satisfying
some condition or set of conditions

Axis of Symmetry A line perpendicular to the
directrix passing through the vertex of a parabola
