Question

Triangle XYZ has vertices X(–1, –3), Y(0, 0), and Z(1, –3). Malik rotated the triangle 90° clockwise about the origin. What is the correct set of image points for triangle X’Y’Z’?

Answer 1

The general rule for a reflection 90º clockwise is (y,-x)
So use that rule to find the new points (Perhaps also include the answer choice graphs)

(-1,3) -> (y,-x)
(0,0) -> (y,-x)
(1,-3) -> (y,-x)
