a is correct  hope this helps 

The correct answer is:

A. Correct. He transformed the triangle according to the rule (x, y) --> (-y, x).

Explanation:

The coordinates of the pre-image are:

F(3, 2); G(1, 2); and H(4, 5)

The coordinates of the image are:

F'(-2, 3); G'(-2, 1); and H'(-5, 4)

The x- and y-coordinates have been switched, and the y-coordinate has been negated.  Algebraically, (x, y)→(-y, x).  Yes, he performed it correctly.
