Do you remember?

Which of the following is a conic?

• Circle

• Rectangle

• Square

• Line

The following are conic sections except for:

• Circle

• Ellipse

• Point

• Parabola

The fixed point of the conic.

• Vertex

• Generator

• Eccentricity

• Focus

The fixed straight line of the conic.

• Focus

• Directrix

• Eccentricity

• Axis

The point of intersection of the conic and the principal axis.

• Focus

• Directrix

• Vertex

• Axis

The line that passes through the fixed point of the conic and the perpendicular to the fixed straight line.

• Focus

• Axis

• Directrix

• Eccentricity

It refers to the value wherein the distance between the point on the conic and the fixed point divided by the distance of the point on the conic and the point which is a projection on the fixed line.

• Focus

• Circle

• Ellipse

• Point

• Line

• Pair of Intersecting Lines

It is defined as a set of points whose distances from a fixed point called the focus are in constant ratio to their distances from a fixed line (directrix) that is not passing through a fixed point.
