Starting with the two quadrilaterals, we see that they have the same shape, size, and orientation. What separates them is their position on the coordinate plane. By translating ABCD by 7 units to the right and 3 units down, we can map ABCD onto EFGH. Therefore, they are congruent.
Regarding △STR and △QPO, they seem to have the same shape and size. However, since they have both different orientation and location, we are likely dealing with a rotation about the origin. Let's rotate △QPO about the origin 90∘.
As we can see, a rotation 90∘ about the origin maps △QPO onto △STR. Therefore, they are congruent. Regarding the final two triangles we see that they do not have the same shape. This means they can't be congruent.
