Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

The result is (x, -y).

Front

What is the result of reflecting a point (x, y) over the y-axis?

Back

The result is (-x, y).

Front

What is the definition of reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the x-axis?

Back

The x-axis is the horizontal axis in a Cartesian coordinate system.

Front

What is the y-axis?

Back

The y-axis is the vertical axis in a Cartesian coordinate system.

Front

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

Back

The reflection of point A over the x-axis is (3, -4).

Front

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

Back

The reflection of point B over the y-axis is (2, 5).

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.

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 is the shape of the reflection of a triangle over the x-axis?

Back

The reflection will be a triangle that is flipped over the x-axis, maintaining the same size and shape.
