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 is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected, such as the x-axis or y-axis.

Front

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

Back

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

Front

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

Back

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

Front

What are the coordinates of the origin in the coordinate plane?

Back

(0, 0)

Front

If point A is at (3, 4), what are the coordinates of its reflection over the x-axis?

Back

(3, -4)

Front

If point B is at (-2, 5), what are the coordinates of its reflection over the y-axis?

Back

(2, 5)

Front

What is the effect of reflecting a point across the y-axis on its x-coordinate?

Back

The x-coordinate becomes its opposite.

Front

What is the effect of reflecting a point across the x-axis on its y-coordinate?

Back

The y-coordinate becomes its opposite.

Front

Which axis is used for reflecting a point to create a mirror image on the opposite side?

Back

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