Reflections

Front

What is the definition of reflection in geometry?

Back

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

Front

What is the ordered pair format?

Back

An ordered pair is written as (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

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

Back

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

Front

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

Back

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

Front

Reflect the point (4, 5) over the y-axis. What is the new point?

Back

(-4, 5)

Front

Reflect the point (-3, -2) over the x-axis. What is the new point?

Back

(-3, 2)

Front

What is the result of reflecting the point (0, 0)?

Back

The point remains (0, 0) because it is on the line of reflection.

Front

If point A is at (2, 3), what is the reflection of point A over the y-axis?

Back

(-2, 3)

Front

If point B is at (-1, 4), what is the reflection of point B over the x-axis?

Back

(-1, -4)

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped to create a mirror image.
