Answer: One set of corresponding sides:
![(AB)/(PQ)=(BC)/(QR)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u9oa1lq3dsfvpd2ebzdlpfwv3s4v0seolz.png)
Explanation:
From figure attached: Polygon ABCD and Polygon PQRS
Given that Polygon ABCD and Polygon PQRS are similar
In similar polygons, corresponding sides are equal in proportion.So, it will be correct write:
![(AB)/(PQ)=(BC)/(QR)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u9oa1lq3dsfvpd2ebzdlpfwv3s4v0seolz.png)
