Rotate  A(3,-1), B(4,-1), C(4,-5) 90 degrees clockwise around (2,-1)

Step 1 , translate so that the rotation point is the origin, by subtracting (2,-1)

A''(1, 0), B''(2, 0), C(2, -4)

Step 2, rotate 90 degrees clockwise.  (x,y) becomes (y,-x)

A'''(0,-1), B'''(0, -2),  C'''(-4, -2)

Step 3, translate back, adding (2,-1)

A'(2, -2), B'(2, -3), C'(-2,-3)

Answer: Draw the triangle with vertices (2, -2), (2, -3), (-2,-3)
