Reflections over the Coordinate Plane

Front

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 its sign, while the y-coordinate remains the same.

Front

Reflect the point (2, -4) over the y-axis. What is the new point?

Back

(-2, -4)

Front

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

Back

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

Front

Reflect the point (3, 5) over the x-axis. What is the new point?

Back

(3, -5)

Front

What is the result of reflecting the point (-1, 4) over the y-axis?

Back

(1, 4)

Front

What is the result of reflecting the point (0, -3) over the x-axis?

Back

(0, 3)

Front

When reflecting a point across both axes, what happens to its coordinates?

Back

Both the x and y coordinates change their signs.

Front

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

Back

(-2, 3)

Front

What is the reflection of the point (4, 0) over the y-axis?

Back

(-4, 0)
