A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
A cone is classified as a three-dimensional geometric shape. It is considered a regular shape when it has a circular base and a single vertex at the top, forming a uniform structure. However, if the base is not circular or the sides are distorted, it can be referred to as an irregular shape. Thus, whether a cone is regular or irregular depends on its specific dimensions and proportions.
A bicone is a three-dimensional shape swept by revolving an isosceles triangle around its base of unequal length, or by joining two identical right circular cones, base to base.
