Translation, Rotation, Reflection

Front

What is the rule for reflection across the y-axis?

Back

The rule for reflection across the y-axis is (x, y) → (−x, y).

Front

How do you write an ordered pair in coordinate geometry?

Back

An ordered pair is written as (X, Y).

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

How do you describe a translation in geometry?

Back

A translation is a transformation that moves a figure a certain distance in a specified direction.

Front

What does it mean to translate a shape 3 units to the right and 4 units up?

Back

It means to move the shape 3 units in the positive x-direction and 4 units in the positive y-direction.

Front

What is the rule for reflection across the x-axis?

Back

The rule for reflection across the x-axis is (x, y) → (x, −y).

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a fixed point, while reflection flips it over a line.

Front

How do you determine the image of a point after a 90-degree rotation counterclockwise?

Back

The image of a point (x, y) after a 90-degree rotation counterclockwise is (-y, x).

Front

What is the effect of a translation on the coordinates of a point?

Back

A translation adds specific values to the x and y coordinates of a point.

Front

What is the definition of rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point by a certain angle.
