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 it mean for shapes to be congruent after a translation?

Back

Congruent shapes are identical in shape and size, meaning they have the same dimensions and angles, even if their positions differ.

Front

How do you translate a shape on a coordinate plane?

Back

To translate a shape, you add or subtract values from the x-coordinate and/or y-coordinate of each point of the shape.

Front

What is the effect of translating a shape 5 units to the right and 3 units up?

Back

The x-coordinates of the shape's points increase by 5, and the y-coordinates increase by 3.

Front

What coordinate is affected when translating a shape up or down?

Back

The y-coordinate is affected when translating a shape up or down.

Front

What is the result of a transformation called?

Back

The result of a transformation is called the image.

Front

If triangle A'B'C' is translated to triangle ABC, what does this imply?

Back

It implies that triangle A'B'C' has been moved to a new position without changing its shape or size.

Front

What is the difference between a pre-image and an image?

Back

The pre-image is the original shape before transformation, while the image is the shape after transformation.

Front

What does it mean to translate a shape left?

Back

Translating a shape left means subtracting from the x-coordinates of the shape's points.

Front

What does it mean to translate a shape down?

Back

Translating a shape down means subtracting from the y-coordinates of the shape's points.
