Answer:
Angle PQR
Explanation:
Polygon ABCD was scaled to get polygon PQRS, of which is similar to polygon ABCD geometrically, in terms of shape.
The angle in polygon PQRS (scaled copy) that corresponds to angle ABC in the original copy, polygon ABCD, is the angle that matches angle ABC and takes the same position as angle ABC.
Thus, angle PQR in polygon PQRS corresponds to angle ABC in polygon ABCD.
