CONICS
The curves obtained by the intersection of a cone by cutting plane in different positions are called conics.

DEFINING CONICSCurve 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 Plane < Angle of Generator
Rectangular Hyperbola Parallel to the Axis and
Perpendicular to the Base

ELLIPSE
Ellipse is defined as the locus of points the sum of whose distances from two fixed points, called the foci, is a constant.

PARABOLA
Parabola is defined as the locus of points whose distances from a fixed point, called the focus, and a fixed line, called the directrix, are always equal.

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

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.
