Which set of transformations would prove δqrs ~ δuts?
a. reflect δuts over y = 2, and dilate δu′t′s′ by a scale factor of 2 from point s.
b. reflect δuts over y = 2, and translate δu′t′s′ by the rule (x − 2, y + 0).
c. translate δuts by the rule (x + 0, y + 6), and reflect δu′t′s′ over y = 6.
d. translate δuts by the rule (x − 2, y + 0), and reflect δu′t′s′ over y = 2.
