Conic Vocabulary

the line segment that has as its endpoints the vertices of a hyperbola

• Transverse axis

• Conjugate axis

• Minor axis

• Major axis

fixed point in a plane where all radii of that circle commence

• Circle

• Center of a circle

• Vertex of a conic section

• Ellipse

the segment perpendicular to the transverse axis of a hyperbola through its center

• Minor axis

• Transverse axis

• Major axis

• Conjugate axis

a pair of special points used in describing conic sections. A circle and a parabola have one focus; an ellipse and a hyperbola have two foci.

• Foci
