Question

A reflection over he line y=x

A counterclockwise rotation of 270 degrees about the origin

A reflection over the line y = -x

A counterclockwise rotation of 180 degrees about the origin

Which answer is it ?

Answer 1

D. A counterclockwise rotation of 180 degrees about the origin

Explanation:

The correct answer would be choice "D" from a process of elimination. The shape has not been reflected, otherwise it wouldn't be flipped to the side, ruling out "A" and "C."

So now we have either a 270 cc rotation, or a 180 rotation. A 270 degree rotation would bring the shape to a quadrant near it, instead of across from it. So this gives you the answer of a counterclockwise rotation of 180 degrees about the origin.
