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 (x, y) when it is reflected over the x-axis?

Back

The coordinates become (x, -y).

Front

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

Back

The coordinates become (-x, y).

Front

If point A(3, 4) is reflected over the x-axis, what are the coordinates of A'?

Back

A' is (3, -4).

Front

If point B(-2, 5) is reflected over the y-axis, what are the coordinates of B'?

Back

B' is (2, 5).

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.

Front

What is the result of reflecting the point (0, 0) over any axis?

Back

The result is still (0, 0) because it is the origin.

Front

How do you determine if a figure is reflected over the x-axis or y-axis?

Back

Check the signs of the y-coordinates for x-axis reflection and x-coordinates for y-axis reflection.

Front

What is the reflection of the point (6, -3) over the x-axis?

Back

The reflection is (6, 3).

Front

What is the reflection of the point (-4, 2) over the y-axis?

Back

The reflection is (4, 2).
