Reflection Over X-Axis and Y-Axis

Front

What is reflection in geometry?

Back

When you flip or mirror an object across a line.

Front

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

Back

The new coordinates will be (x, -y).

Front

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

Back

The new coordinates will be (-x, y).

Front

What are the coordinates of the point O?

Back

(0, -6)

Front

If the point (5, -3) is reflected over the x-axis, what are the new coordinates?

Back

(5, 3)

Front

If the point (5, -3) is reflected over the y-axis, what are the new coordinates?

Back

(-5, -3)

Front

What is the result of reflecting the point (5, -3) first over the x-axis and then over the y-axis?

Back

(-5, 3)

Front

What does it mean to reflect a shape over a line?

Back

To create a mirror image of the shape across that line.

Front

What is the line of reflection?

Back

The line across which a figure is reflected.

Front

If a point is reflected over both axes, what happens to its coordinates?

Back

Both x and y coordinates change signs.
