Answer:
A
Explanation:
When a point (x,y) is rotated 90 degrees counterclockwise about the origin our point becomes (-y, x).
Point E is at (6, -3)
If we translate by (x-6,y+3), we have: (6-6,-3+3)=(0,0)
Rotating it 90 degrees counterclockwise about the origin gives the coordinate: (0, 0).
This is equivalent to the coordinate of corresponding vertex B.
The correct choice is A.
