What is a translation?

Back

A translation moves a shape from one place to another without changing its size, shape, or orientation.

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

Back

Reflecting across the y-axis means flipping a shape over the vertical line (y-axis), changing the sign of the x-coordinates.

What is the scale factor in dilation?

Back

The scale factor is the number that tells how much larger or smaller a shape will be after dilation.

What is the difference between translation and reflection?

Back

Translation moves a shape without changing its orientation, while reflection flips it over a line.
