y-coordinate

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is a reflection in geometry?

Back

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

Front

What happens to the x-coordinate when a figure is reflected over the y-axis?

Back

The x-coordinate changes sign (x becomes -x).

Front

What happens to the y-coordinate when a figure is reflected over the x-axis?

Back

The y-coordinate changes sign (y becomes -y).

Front

If a point A(2, 3) is translated 4 units right and 2 units up, what are the coordinates of the new point A'?

Back

A'(6, 5)
