Reflections 1

Front

What is a reflection in geometry?

Back

A reflection is when you flip an image across a line, creating a mirror image.

Front

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

Back

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

Front

What is the reflection of the point (3, 4) over the y-axis?

Back

The reflection is (-3, 4).

Front

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

Back

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

Front

What is the reflection of the point (2, -5) over the x-axis?

Back

The reflection is (2, 5).

Front

If point A is at (1, 2), where will A' be if reflected over the y-axis?

Back

A' will be at (-1, 2).

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 is the reflection of the point (-4, 3) over the x-axis?

Back

The reflection is (-4, -3).

Front

If triangle ABC is reflected over the y-axis, what happens to the coordinates of its vertices?

Back

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

Front

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

Back

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