P. 2 Translations and Reflections Practice 2024

Front

What is a reflection in geometry?

Back

A reflection is 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 line of reflection is the x-axis.

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

Back

(4, -5)

Front

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

Back

The line of reflection is the y-axis.

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

Back

(2, 3)

Front

When translating a point up on a coordinate plane, which coordinate is affected?

Back

The y-coordinate is affected.

Front

When translating a point down on a coordinate plane, which coordinate is affected?

Back

The y-coordinate is affected.

Front

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

Back

The rule is (x, -y).
