Reflections

Front

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

Back

(x, y) → (x, -y)

Front

If the point K is (1, -4), what are the coordinates of K' after reflecting across the x-axis?

Back

(1, 4)

Front

What are the coordinates of point I' if point I is (2, -6) and is reflected across the x-axis?

Back

(2, 6)

Front

Reflect the point (6, -3) over the x-axis. What are the new coordinates?

Back

(6, 3)

Front

What transformation occurs when a figure is reflected across the x-axis?

Back

The y-coordinates of all points change sign.

Front

Define reflection in geometry.

Back

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

Front

What is the line of reflection for a reflection across the x-axis?

Back

The x-axis itself.

Front

If point A is at (3, 5), what are the coordinates of A' after reflection across the x-axis?

Back

(3, -5)

Front

How does reflecting a point across the x-axis affect its distance from the x-axis?

Back

The distance remains the same; only the direction changes.

Front

What is the effect of reflecting a triangle across the x-axis?

Back

The triangle's orientation is flipped vertically.
