Front

What is the definition of reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

What happens to the y-coordinate when reflecting a point over the x-axis?

Back

The y-coordinate changes sign.

Front

If a point is at (x, y), what will its coordinates be after reflecting over the y-axis?

Back
