Answer:
Polygon PQRST cannot be mapped onto the others by similarity transformations.
Explanation:
A similarity transformation has many rigid transformations like- reflection, rotation, translation etc.
When any given figure is transformed by using any similarity transformation, the resulting image created is similar to the original image.
Here, the only image that cannot be mapped on others is PQRST.
Otherwise, ABCDE is similar to FGHIJ and KLMNO is similar to UVWXY.
