How do you perform a reflection over the y-axis?

Back

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate: the new point is (-x, y).

What is the result of rotating a point 180° about the origin?

Back

Rotating a point (x, y) 180° about the origin results in the point (-x, -y).
