A shape looks the same when rotated by $90°$. What is the order of its rotational symmetry?

The following question consists of two sets of figures. There is a definite relationship between the first set of figures. Establish a similar relationship between the second set of figures by selecting a suitable figure from the options.

Graph the image of the quadrilateral $ABCD$ after a dilation with a scale factor of $3$, centered at the origin.

Does the following figure have rotational symmetry of order more than $1$?

Give the order of rotational symmetry for each of the following figures when rotated about the marked point (x):

Describe the transformation that has been performed in the diagram and express it using correct arrow notation. 

Graph the image of the triangle $ABC$ after a dilation with a scale factor of $\frac{1}{3}$, centered at the origin.
