(8 cards)
1
Q
a curve formed by a
plane passing through double-napped circular cone.
A
conic section (or conic),
2
Q
are formed when the intersection
of cone and plane is a bounded curve.
A
circle and ellipse
3
Q
is a special
case of the ellipse in which the plane is perpendicular to
the axis of the cone.
A
Circle
4
Q
If the plane is parallel to a generator line of the cone, the conic is:
A
parabola
5
Q
if the intersection is unbounded curve and the plane is not parallel to a generator line of the cone and the
plane intersects both halves of the cone, the conic is a:
A
hyperbola
6
Q
Set of all points on a plane that are equidistant from a fixed point on a plane.
A
Circle
