Which transformation on quadrilateral 1 can be used to verify that is similar to quadrilateral?

Given
Two quadrilaterals on a plane.
Required
we need to find what transformation can be done on quadrilateral 1 to verify it is similar to quadrilateral 2.
Explanation
Since the two quadrilaterals are aligned in terms of angles and sides.
So the only transformation we need to make is to dilate quadrilateral 1 and we can verify it is similar to quadrilateral 2.
So the required transformation is dilation or scaling it down.
