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 happens to the coordinates of a point when it is reflected over the x-axis?

Back

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

Front

What happens to the coordinates of a point when it is reflected over the y-axis?

Back

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

Front

If point A (x, y) is reflected over the x-axis, what are the coordinates of the reflected point A'?

Back

A' will be (x, -y).

Front

If point B (x, y) is reflected over the y-axis, what are the coordinates of the reflected point B'?

Back

B' will be (-x, y).

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected, creating a mirror image.

Front

How do you reflect a point across the x-axis?

Back

To reflect a point (x, y) across the x-axis, change the sign of the y-coordinate to get (x, -y).

Front

How do you reflect a point across the y-axis?

Back

To reflect a point (x, y) across the y-axis, change the sign of the x-coordinate to get (-x, y).

Front

What is the result of reflecting the point (3, 4) over the x-axis?

Back

The reflected point is (3, -4).

Front

What is the result of reflecting the point (-2, -5) over the y-axis?

Back

The reflected point is (2, -5).
