A square with sixes 6 units in length is reflected across the x-axis. How long are the sides in the reflected figure?

Answer 1

When a shape is reflected across the x-axis, its dimensions do not change; only its position in the coordinate plane does. Therefore, if you have a square with sides that are 6 units in length, after reflecting it across the x-axis, the sides of the reflected square will still be 6 units in length.

So, the sides in the reflected figure are still 6 units long.
