Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
A circle, square, and a triangle all have rotational symmetry.
These are also known as asymmetric shapes.
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
Square, circle, equilateral triange! Hope I helped! :)
