Translations Extended Practice

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

When translating a figure up or down, which coordinate is affected?

Back

The y-coordinate is affected.

Front

If a shape is translated to the left, will its mapping notation involve addition or subtraction?

Back

Subtraction is used in the mapping notation.

Front

What happens to the coordinates of a point when it is translated up?

Back

The y-coordinate increases.

Front

What happens to the coordinates of a point when it is translated down?

Back

The y-coordinate decreases.

Front

What happens to the coordinates of a point when it is translated left?

Back

The x-coordinate decreases.

Front

What happens to the coordinates of a point when it is translated right?

Back

The x-coordinate increases.

Front

What is the mapping notation for translating a point (x, y) 4 units to the right and 3 units down?

Back

(x + 4, y - 3) is the mapping notation.

Front

Identify the transformation from ABC to A'B'C' if the mapping is (x + 8, y + 4).

Back

The transformation is a translation 8 units to the right and 4 units up.

Front

If a shape is translated down, will its mapping notation have addition or subtraction?

Back

Subtraction is used in the mapping notation.
