Answer:
Step-by-step explanation:
It is a little vague on what the expected answer is. But for quadrilaterals, any rotational symmetry will be along a line that divides the quadrilaterals in two equal halves. This is due to symmetry.
Also the two equal halves will be mirror image of each other at the axis of symmetry. It is again due to properties of symmetry.
Lastly rotating a quadrilateral along its axis of rotational symmetry will create a 3-D cylindrical shape. A cross-section of that shape along the axis will show the same quadrilateral.
