  Cone

A cone is a body that consists of a circle - the base of the cone , a point not lying in the plane of this circle - the vertices of the cone and all the segments connecting the vertex of the cone with the points of the base. The segments connecting the vertex of the cone with the points of the circumference of the base are called the generators of the cone .
A cone is called straight if the straight line connecting the vertex of the cone with the center of the base is perpendicular to the plane of the base.
The height of the cone is called the perpendicular dropped from its top to the plane of the base.
