Geometry

Question Analysis:
This problem tests the ability to reverse engineer a transformation rule into a sequence of known isometries.
The main focus is identifying how rotation affects coordinates, and how translation is layered on top.

Key Concept Explanation:
Rotation 270° CCW = 90° clockwise: (x, y) → (y, −x)
Then apply translation:
 x → x − 1 (left 1)
 y → y − 2 (down 2)

Step-by-Step Solution:
Start with rotation: (x, y) → (y, −x)
Apply translation:
 x = y → y − 1
 y = −x → −x − 2
Final result: → (y − 1, −x − 2) ✅

Option Analysis:
A: Rotation direction is wro...
