Definition
Cones are classified according to the shape of the base, for example:
Circular Cone
A circular cone is a cone which has a base whose shape is a circle.
Elliptical Cone
An elliptical cone is a cone which has a base whose shape is an ellipse.
Right Cone
A right cone is a cone which has an axis which is perpendicular to its base.
Oblique Cone
An oblique cone is a cone whose apex does not intersect a perpendicular through the center of its base.
Right Circular Cone
A right circular cone is a cone:
- whose base is a circle
- in which there is a line perpendicular to the base through its center which passes through the apex of the cone:
- which is made by having a right-angled triangle turning along one of the sides that form the right angle.
