A combination glue head consisting of several individual glue heads, in addition to the glue head, can be cut, which is also a special use of the existing glue head.
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.

Ellipses (and, in the special case circles).
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
unlike other shapes a sphere is round
in 2d shapes a quadrilateral
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
