Reflections

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 line is used for reflecting a figure to create a mirror image?

Back

The line of reflection, which can be the x-axis, y-axis, or any other line.

Front

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

Back

The x-coordinates of the points change sign, while the y-coordinates remain the same.

Front

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

Back

The y-coordinates of the points change sign, while the x-coordinates remain the same.

Front

What is the color of the x-axis in a standard Cartesian coordinate system?

Back

Red.

Front

What is the color of the y-axis in a standard Cartesian coordinate system?

Back

Black.

Front

How do you reflect a point (3, 2) over the y-axis?

Back

The reflected point is (-3, 2).

Front

How do you reflect a point (-4, -5) over the x-axis?

Back

The reflected point is (-4, 5).

Front

What is the equation of the line used to reflect a figure over the line y = -4?

Back

The line y = -4 is a horizontal line that runs through the point (0, -4).

Front

If a figure is reflected over the x-axis, what is the new position of the point (2, 3)?

Back

The new position is (2, -3).
