conic section
the intersection of a plane with one or both nappes of a double cone
circle
the locus of points in a plane that are equidistant from one point, called the center
ellipse
the locus of points in a plane such that the sum of the distances from any point in the locus to two points, called the foci, is a constant
hyperbola
the locus of points in a plane such that the difference of the distances to the two fixed points called the foci is a constsnt
parabola
the locus of points in a plane that are equidistant from a line and a point not on the line
major axis
the line through the vertices of an ellipse
transverse axis
the line joining the two vertices of a hyperbola
directix
the line, along with a point not on the line, which is used to generate a parabola
eccentricity
a measure of how close an ellipse is to being circular
asymptote
one of two lines through the center of a hyperbola that the hyperbola approaches but never intersects
focus
one of two points such that the difference of the distances from any point on the hyperbola to the foci is a constant
