Front

What is the effect of a 180-degree rotation on the coordinates of a point?

Back

It reflects the point through the origin, changing both coordinates to their opposites.

How does a 90-degree rotation counterclockwise affect the coordinates of a point?

Back

It switches the coordinates and changes the sign of the new x-coordinate.
