What is a reflection in geometry?

Back

A reflection in geometry is a transformation that flips a figure over a line, creating a mirror image.

Front

What happens to the coordinates 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

Reflect the point (3, 4) over the y-axis. What is the new point?

Back

(-3, 4)

Front

What happens to the coordinates 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 (-5, 2) over the x-axis. What is the new point?

Back

(-5, -2)

Front

If point A is at (1, 2), what is the reflection of point A over the y-axis?

Back

(-1, 2)

Front

If point B is at (-3, -4), what is the reflection of point B over the x-axis?

Back

(-3, 4)

Front

What is the reflected point of (0, 5) over the y-axis?

Back

(0, 5) - it remains the same because it lies on the y-axis.

Front

If you reflect point D (4, -1) over the y-axis, what is the reflected point?

Back

(-4, -1)

Front

If you reflect point E (-2, 3) over the x-axis, what is the reflected point?

Back

(-2, -3)
