• Parabola

  Let F1 and F2 be two distinct points and I a given line not containing F. The set of all points P such that its distance from F and from I are the same 1 is called
• Hyperbola

  Let F1 and F2 be two distinct points. The set of all points P, whose distances from F2 differ by F1 and from F2 is called
• 0,0

  Given the standard equation of a circle x²+y² = 25 the center is
• Directrix This line divides the parabola into two parts which are mirror images of each other .
• Downward In a parabola, if the x part is squared and IS negative, the parabola is?
• asymtopes Two lines passing through the center which serve as a graphing the hyperbola
• Circle guide in The set of all points P having the same distance from C is called
• ellipse

  The orbits of the planets in our solar system around the sun happen to be in a shape of
• foci

  Each focus is c units away from the center.
• vertices

  are points on the ellipse, collinear with the center and foci.
• Axis of symmetry and directrix

  This line divides the parabola into two parts which are mirror images of each other
• covertices • The segment through the center, perpendicular to the major axis. It divides the ellipse into two congruent parts.
