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

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

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

Reflect the point (2, -4) over the y-axis.

Back

(-2, -4)

Front

When you reflect a point over the x-axis, what changes?

Back

The y-coordinate changes.

Front

Reflect (-2, 5) over the x-axis.

Back

(-2, -5)

Front

Reflect (8, 4) over the x-axis.

Back

(8, -4)

Front

Reflect point B (-2, 5) over the y-axis. What is the reflected point?

Back

B' (2, 5)

Front

What is the result of reflecting the point (0, 3) over the y-axis?

Back

(0, 3) - The point remains the same because it lies on the y-axis.

Front

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

Back

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