Answer: D': (-7, -1)
E': (-6, -1)
F': (-6, -10)
G': (-7, -10)
Explanation:
In a 90 degree clockwise rotation about the origin for this rectangle, the x and y coordinates of the rectangle's edges are swapped, but the y-coordinates are negated. This is because the transformation is happening to the 3rd quadrant, where both the x and y values will be negative.
D: (1, -7) ==> (-7, 1) ==> D': (-7, -1)
E: (1, -6) ==> (-6, 1) ==> E': (-6, -1)
F: (10, -6) ==> (-6, 10) ==> F': (-6, -10)
G: (10, -7) ==> (-7, 10) ==> G': (-7, -10)
