What is the transformation from ABC to A'B'C' if it is a reflection across the x-axis?

Back

The coordinates of the reflected points will have their y-values changed in sign.

Front

What does it mean to reflect a shape across the y-axis?

Back

The x-values of the points are changed in sign, while the y-values remain the same.

Front

When a point is reflected over the x-axis, what happens to its coordinates?

Back

Keep the x-value, change the y-value.
