In which case does the transformation of △𝑄𝑅𝑆 result in an image △𝐷𝐸𝐹 where ∠𝑄≅∠𝐷,∠𝑅≅∠𝐸,∠𝑆≅∠𝐹, and 𝑄𝑅𝐷𝐸=𝑄𝑆𝐷𝐹=𝑅𝑆𝐸𝐹≠1 ?

• A. a translation of 6 units to the left and 8.5 units up followed by a reflection over the line 𝑦=2𝑥

• B. a reflection over the line 𝑦=−2𝑥 followed by a translation of 6.5 units to the right and 3.5 units down

• C. a rotation of 45° clockwise about vertex 𝐴 followed by a dilation by a scale factor of 0.95 about the origin.

• D. a dilation by a scale factor of 1 about the origin followed by a rotation of 45° clockwise about vertex 𝐴
