Translations

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a shape the same distance in a specified direction.

Front

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

Back

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

Front

What is the result of a translation called?

Back

The result of a translation is called the image.

Front

If a shape is translated 3 units to the right and 2 units up, what is the translation vector?

Back

The translation vector is (3, 2).

Front

How do you translate a point (x, y) to the left by 4 units?

Back

To translate (x, y) to the left by 4 units, the new coordinates will be (x - 4, y).

Front

What is the effect of translating a shape 0 units in the x-direction?

Back

Translating a shape 0 units in the x-direction means it will not move horizontally.

Front

How do you determine the new coordinates of a point after translation?

Back

Add the translation values to the original coordinates: (x + horizontal shift, y + vertical shift).

Front

What is the translation of quadrilateral EFGH to E'F'G'H' if it moves 6 down and 3 left?

Back

The translation is represented as (0, -6) for down and (-3, 0) for left.

Front

If triangle A'B'C' is translated to triangle ABC, what does it mean?

Back

It means that triangle A'B'C' has been moved to a new position to become triangle ABC.

Front

What is the difference between a translation and a rotation?

Back

A translation moves a shape without changing its orientation, while a rotation turns a shape around a fixed point.
