Reflection Practice

Front

What is reflection in geometry?

Back

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

Front

What is the rule for reflecting a point (x, y) over the y-axis?

Back

The rule is (x, y) → (-x, y).

Front

What is the rule for reflecting a point (x, y) over the x-axis?

Back

The rule is (x, y) → (x, -y).

Front

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

Back

A'(-3, 4).

Front

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

Back

B'(-2, -5).

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.

Front

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

Back

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

Front

Reflect the point (1, -3) over the y-axis. What are the new coordinates?

Back

(-1, -3).

Front

Reflect the point (-4, 2) over the x-axis. What are the new coordinates?

Back

(-4, -2).

Front

What is the effect of reflecting a shape across the y-axis?

Back

The shape's orientation is reversed horizontally, while its vertical position remains unchanged.
