Translations and Reflections

Front

What is the result of reflecting the point Y(-5, -7) over the y-axis?

Back

The reflected point is (5, -7).

Front

When reflecting a point over the y-axis, which coordinate changes?

Back

The x-coordinate changes.

Front

What are the coordinates of point I' if triangle GHI is reflected across the x-axis and point I is at (6, -2)?

Back

The coordinates of I' are (6, 2).

Front

If a figure is reflected over the x-axis, what happens to the y-coordinates of its points?

Back

The y-coordinates change sign (y becomes -y).

Front

When translating a figure on a coordinate plane, which coordinate is affected by movement left and right?

Back

The x-coordinate is affected.

Front

What is the effect of reflecting a point across the x-axis?

Back

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

Front

If a point A(3, 4) is reflected over the y-axis, what are the new coordinates?

Back

The new coordinates are A'(-3, 4).

Front

What is the definition of translation in geometry?

Back

Translation is the process of moving a figure from one position to another without changing its shape or orientation.

Front

How do you reflect a point across the line y = x?

Back

To reflect a point (a, b) across the line y = x, swap the coordinates to get (b, a).

Front

What happens to the coordinates of a point when it is translated 3 units to the right and 2 units up?

Back

The new coordinates will be (x + 3, y + 2).
