4. CONICS
The curves obtained by
the intersection of a cone
by cutting plane in
different positions are
called conics.
The conics are
1.CIRCLE
2.ELLIPSE
3.PARABOLA
4.HYPERBOLA

6. DEFINING CONICS
CurvE
Position of Cutting Plane
CIrClE
Perpendicular to axis and parallel to
the base
EllIpSE
Inclined to the axis and not parallel
to any generator. Angle of Cutting
Plane > Angle of Generator
parabOla
Inclined to axis, parallel to
generators and passes through the
base and axis
HypErbOla
Inclined to the axis and not parallel
to any generator. Angle of Cutting

7. EllIpSE
Ellipse is
defined as
the locus of
points the
sum of whose
distances
from two
fixed points,

8. parabOla
Parabola is
defined as
the locus of
points whose
distances
from a fixed
point, called
the focus,
and a fixed

9. HYPERBOLA
Hyperbola is
defined as the
locus of points
whose distances
from two fixed
points, called
the foci,
remains
constant.

10. INVOLUTES
> An involutes is a curve traced by a
point as it unwinds from around a circle or
polygon.
> The concerned circle or polygon is called
as Involutes.
