Translations

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 does the transformation (x, y) --> (x, y + 4) indicate?

Back

It indicates a slide up 4 units.

Front

What is the image in a transformation?

Back

The image is the result of a transformation applied to a pre-image.

Front

How do you describe the translation from point B to B' if B' is at (4, -2)?

Back

B was translated 2 units to the right and 6 units down.

Front

What are the new coordinates of point M (-3, 5) after the translation (x, y) --> (x - 1, y)?

Back

The new coordinates are (-4, 5).

Front

What is the rule for translating a point 2 units to the right and 6 units down?

Back

The rule is (x + 2, y - 6).

Front

What does the term 'pre-image' refer to in transformations?

Back

The pre-image is the original figure before any transformation is applied.

Front

If a point is translated using the rule (x + 3, y - 2), what happens to the y-coordinate?

Back

The y-coordinate decreases by 2.

Front

What is the effect of translating a point 5 units left?

Back

The x-coordinate of the point decreases by 5.

Front

How can you represent a translation that moves a point 4 units up and 3 units left?

Back

The translation can be represented as (x - 3, y + 4).
