Reflections across the x and y axis Extra Practice

Front

What is a reflection in geometry?

Back

A reflection is when you flip or mirror an object across a line.

Front

Reflect the point (4, 5) over the x-axis. What is the coordinate of its image?

Back

(4, -5)

Front

Reflect the point (3, -2) over the y-axis. What is the coordinate of its image?

Back

(-3, -2)

Front

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

Back

The x-coordinate changes sign.

Front

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

Back

The y-coordinate changes sign.

Front

Reflect the point (-1, 2) over the x-axis. What is the coordinate of its image?

Back

(-1, -2)

Front

Reflect the point (0, -3) over the y-axis. What is the coordinate of its image?

Back

(0, -3)

Front

If point A is at (2, 3), what are the coordinates of point A' after reflecting over the x-axis?

Back

(2, -3)

Front

If point B is at (-4, -1), what are the coordinates of point B' after reflecting over the y-axis?

Back

(4, -1)

Front

Reflect the point (5, 0) over the x-axis. What is the coordinate of its image?

Back

(5, 0)
