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 result of a transformation called?

Back

The result of a transformation is called the Image.

Front

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

Back

The transformation is a slide right 8 units and slide up 4 units.

Front

Write the rule for sliding a point 3 units up and 2 units right.

Back

The rule is (x, y) --> (x + 2, y + 3).

Front

When translating left or right on a coordinate plane, which coordinate is affected?

Back

The x-coordinate is affected.

Front

What is the pre-image in a transformation?

Back

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

Front

If a point (3, 5) is translated 4 units left and 2 units down, what is the new position?

Back

The new position is (-1, 3).

Front

What does the transformation (x, y) --> (x - 4, y) represent?

Back

It represents a slide left 4 units.

Front

How do you express a translation that moves a point 5 units down?

Back

The expression is (x, y) --> (x, y - 5).
