Question

Right triangle XYZ, with vertex Y at (-3, 0), is rotated clockwise 180° about the origin. Which of the following rotations is equivalent to 180° clockwise rotation about the origin? clockwise 360° counterclockwise 180° counterclockwise 360° clockwise 270°

Answer 1

the answer is counterclockwise 180

Explanation:

Answer 2

the rule for rotation 180 degrees clockwise around the origin is:

(x,y) --------> (-x,-y)

(-3,0) --------> (-(-3),0)

(-3,0) --------> (3,0)

rotation counterclockwise 180 degrees is the same as rotation 180 degrees clock wise:

(x,y) -------->(-x,-y)
