Geometry Translations and Reflections

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a given direction.

Front

What does the rule 'x + 0' indicate in a translation?

Back

It indicates that the x-coordinates of the points remain unchanged during the translation.

Front

What is the effect of a reflection across the y-axis on the coordinates of a point (x, y)?

Back

The coordinates change to (-x, y).

Front

What is the effect of a reflection across the x-axis on the coordinates of a point (x, y)?

Back

The coordinates change to (x, -y).

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 does it mean for translations to be congruent?

Back

It means that the original figure and the translated figure have the same shape and size.

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

Back

The line of reflection is the y-axis.

Front

What is the relationship between translations and congruence?

Back

Translations preserve the size and shape of the figure, making the original and translated figures congruent.

Front

What is the term used for a flip in geometry?

Back

A flip is also called a reflection.
