Translations and Reflections Review

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 specified direction.

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

Do translations preserve congruence?

Back

Yes, translations preserve congruence, meaning the original figure and the translated figure are congruent.

Front

Do reflections preserve congruence?

Back

Yes, reflections also preserve congruence, meaning the original figure and the reflected figure are congruent.

Front

What happens to the orientation of a figure during a reflection?

Back

The orientation of the figure changes during a reflection.

Front

What happens to the orientation of a figure during a translation?

Back

The orientation of the figure remains the same during a translation.

Front

If a figure is reflected across the x-axis, how do the coordinates change?

Back

The y-coordinates of the points change sign, while the x-coordinates remain the same.

Front

If a figure is translated 5 units to the left and 3 units up, how do the coordinates change?

Back

The x-coordinates decrease by 5 and the y-coordinates increase by 3.

Front

What is the result of translating a point (2, 3) 4 units to the right and 2 units down?

Back

The new coordinates will be (6, 1).

Front

What is the result of reflecting a point (4, -5) across the y-axis?

Back

The new coordinates will be (-4, -5).
