CONE A cone is formed by rotating a right-angled triangle with an apex angle 'α' about its altitude as the axis. (Fig. 6.1.) The fixed point about which right angled triangle is rotated is known as apex (or) vertex and an imaginary line joining the apex to the circumference of the base circle is called a generator. The altitude of the right angled triangle (or) the line joining the centre of the base (ie., circle) and the apex is called as the axis of cone. In a right circular cone, the axis of the circular cone is perpendicular to its base.
