How do you describe the movement in a translation?

Back

The movement in a translation is described by the number of units moved horizontally and vertically.

What happens to the coordinates of a point when it is reflected across the x-axis?

Back

The y-coordinate of the point changes sign, while the x-coordinate remains the same.

If triangle ABC is reflected across the line y = 1, how do the coordinates of point A change?

Back

The y-coordinate of point A is adjusted based on its distance from the line y = 1.

What is the effect of a translation on the shape of a figure?

Back

A translation does not change the shape or size of a figure; it only changes its position.
