Front

What does it mean to translate a shape?

Back

To slide a shape from one position to another without changing its size, shape, or orientation.

Front

What does it mean to reflect a shape?

Back

To flip a shape over a line, creating a mirror image.

Front

Back

The horizontal line that runs side to side.

Front

What is the Y-axis on a coordinate grid?

Back

Front

If a shape is translated 3 units to the right, what happens to its coordinates?

Back

The x-coordinates increase by 3.

Front

If a shape is reflected over the X-axis, what happens to its coordinates?

Back

The y-coordinates change sign (positive becomes negative and vice versa).

Front

If a shape is rotated 90 degrees clockwise, how do its coordinates change?

Back

The new coordinates (x', y') become (y, -x).

Front

What is the center of rotation?

Back

The fixed point around which a shape is rotated.
